PyEphem CHANGELOG
=================
Version 3.7.3.4 (2009 April 30)
-------------------------------
- Added a new ``next_pass()`` method to ``Observer`` that searches for
when a satellite next rises, culminates, and sets.
- Added a ``compute_pressure()`` method to ``Observer`` which computes
the standard atmospheric pressure at the observer's current elevation.
This function now gets called automatically on new ``city()`` objects
before they are returned to the user.
- Corrected the altitude of San Francisco as returned by ``city()``.
- Improved the copyright message so that two more authors are credited.
Version 3.7.3.3 (2008 October 3)
--------------------------------
- Added ``cmsI`` and ``cmsII`` attributes to ``Jupiter`` to provide the
central meridian longitude in both System I and System II.
- **Bugfix**: Saturn was returning the wrong values for its earthward
and sunward angle tilt.
Version 3.7.3.2 (2008 July 2)
-----------------------------
- **Bugfix**: the rising and setting functions, if called repeatedly,
would sometimes get hung up on a single answer which they would return
over and over again instead of progressing to the next rising or
setting. They should now always progress instead of getting stuck.
Version 3.7.3.1 (2008 July 1)
-----------------------------
- **Bugfix**: the rising and setting functions were attempting to
achieve such high precision that users sometimes found circumstances
under which they would not complete at all! They now stop and return
an answer once they are withing a half-second of the real time of
rising, transit, or setting, which solves the problem without damaging
the quality of the results when tested against the Naval Observatory.
- Upgraded to the libastro from XEphem 3.7.3.
Version 3.7.2.4 (2008 June 12)
------------------------------
- **Incompatible Change**: After feedback from users, I have changed
the ``Observer`` methods which find risings, settings, and transits,
so that they do not change their Observer's ``.date`` attribute. So
the sequence:
.. code-block:: python
r1 = boston.next_rising(mars)
r2 = boston.next_rising(mars)
now computes the same value twice! If you want a series of calls to
each begin when the other left off, you can use the ``start=``
parameter described in the next item:
.. code-block:: python
r1 = boston.next_rising(mars)
r2 = boston.next_rising(mars, start=r1)
- Added an optional ``start=`` argument to the rising, setting, and
transit ``Observer`` functions, that tells them from which date and
time to begin their search.
- **Bugfix**: Rewrote planetary moon routines so that moons of Mars,
Jupiter, Saturn, and Uranus now return appropriate data for years
1999-2020. (Each moon had been returning the unmodified position of
its planet, because I was unsure whether I could distribute the moon
data with PyEphem.)
- You can no longer create arbitrary attributes on an ``Observer``, to
prevent users from accidentially saying things like
``here.longitude`` or ``here.lon`` when they mean ``here.long``.
Create your own subclass of ``Observer`` if you need the power to
set your own attributes.
- The ephem module now provides a ``__version__`` symbol.
- Added test suite that tests planet and planet moon positions
against JPL ephemeris data (needs more work).
Version 3.7.2.3 (2008 January 8)
--------------------------------
- Three new classes ``Equatorial``, ``Ecliptic``, and ``Galactic``
allow coordinates to be transformed between the three systems
(ability to transform coordinates was requested by Aaron Parsons).
- Added constants for popular epochs ``B1900``, ``B1950``, and
``J2000``.
- Added named functions for every solstice and equinox (before, only
the vernal equinox could be asked for specifically).
- Product tests have been moved inside of the ``ephem`` module itself,
and can now be invoked simply by running:
.. code-block:: bash
$ python setup.py test
- **Bugfix**: ``Angle()`` can no longer be directly instantiated.
- **Bugfix**: San Francisco had the wrong coordinates in the cities
database (pointed out by Randolph Bentson).
Version 3.7.2.2 (2007 December 9)
---------------------------------
- The phases of the moon can now be determined through the functions
``next_new_moon()``, ``next_full_moon()``, ``previous_new_moon()``,
et cetera.
- Added a modest database of world cities; the ``city()`` function
returns a new Observer on each call:
.. code-block:: python
observer = ephem.city('Boston')
- Using the old ``rise``, ``set``, and ``transit`` attributes on
``Body`` objects now causes a deprecation warning.
- **Bugfix**: the last release of PyEphem omitted the constants
``meters_per_au``, ``earth_radius``, ``moon_radius``, and
``sun_radius``; the constant ``c`` (the speed of light) is also now
available.
Version 3.7.2.1 (2007 October 1)
--------------------------------
- Functions now exist to find equinoxes and solstices.
- Bodies now cleanly offer three different versions of their
position, rather than making the user remember obscure rules for
having each of these three values computed:
* Astrometric geocetric right ascension and declination
* Apparent geocentric right ascension and declination
* Apparent topocentric right ascension and declination
- Bodies can now find their next or previous times of transit,
anti-transit, rising, and setting.
- A ``localtime()`` function can convert PyEphem ``Date`` objects to
local time.
- Now ``ephem.angle`` instances can survive unary ``+`` and ``-``
without getting changed into plain floats.
- The ``elev`` Observer attribute has been renamed to ``elevation``.
- Observers now display useful information when printed.
- Added a much more extensive test suite, which, among other things,
now compares results with the United States Naval Observatory,
insisting upon arcsecond agreement.
- **Bugfix**: When a fixed body is repeatedly precessed to different
dates, its original position will no longer accumulate error.
Version 3.7.2a (2007 June)
--------------------------
- Upgraded to the libastro from XEphem 3.7.2.
- Should now compile under Windows!
- **Bugfix**: rewrote date-and-time parsing to avoid the use of
``sscanf()``, which was breaking under Windows and requiring the
insertion of a leading space to succeed.
- Improved the error returned when a date string cannot be parsed,
so that it now quotes the objectionable string (so you can tell
which of several date strings on the same line gave an error!).
3.0200 June 18, 2010
- Added skewness and kurtosis
- https://rt.cpan.org/Ticket/Display.html?id=58187
- Thanks to Shawn Laffan.
3.0102 June 15, 2010
- Add the $VERSION variable to Statistics::Descriptive::Sparse and
Statistics::Descriptive::Full. This was done to silence the CPAN indexer.
3.0101 June 15, 2010
- Moved the trimmed_mean caching test (that used the Benchmark.pm module)
to rejects/descr.t , because it kept failing.
math/p5-Math-Random-MT.
The Mersenne Twister is a pseudorandom number generator developed by
Makoto Matsumoto and Takuji Nishimura. It is described in their paper at
<URL:http://www.math.keio.ac.jp/~nisimura/random/doc/mt.ps>.
CHANGES MADE TO MATHOMATIC 15.2.0 TO BRING IT UP TO THE NEXT VERSION:
All makefiles were improved. Library test/example program is renamed to "testmain".
Package maintainers please take note: support for the DESTDIR environment variable was
added to the makefiles; for proper operation when packaging version 15.2.1 or higher,
please remove any patches for missing DESTDIR support.
m4 Mathomatic should work now when included in the Mathomatic package (make m4install).
Thank you for packaging Mathomatic! If I did anything wrong, please let me know.
8/26/10 - Added the -e option, which processes mathematical expressions and Mathomatic commands
instead of input files on the shell command line. For example, entering
"mathomatic -eq 2+3" gives "answer = 5". This functionality has been requested
many times by Mathomatic command line users. A complete example:
CHANGES MADE TO MATHOMATIC 15.1.6 TO BRING IT UP TO THE NEXT VERSION:
Minor improvements were made to the user documentation.
8/22/10 - Removed "Complex number roots approximated" warning message, since this happens often.
Capitalized E, I, PI, and Pi are now accepted as the universal constants e, i, and pi,
without needing to enter "set no case". This allows Mathomatic to easily
accept Mathematica style expression input.
m4 Mathomatic now additionally accepts Mathematica style capitalized function input.
matho and rmath now display elapsed, CPU, and system times in seconds upon exit.
8/23/10 - Fixed #equation-number entry at the main prompt to always work and allow an expression
or equation following on the same line to be entered at that equation space.
For example: "#10 y=1/x" will work now;
previously only worked if equation space number 10 was previously allocated and used.
The way it works is: all equation spaces up to and including number 10 are allocated,
if not already allocated, upon entry of "#10".
Equations spaces are allocated with the memory allocator malloc(3).
CHANGES MADE TO MATHOMATIC 15.1.5 TO BRING IT UP TO THE NEXT VERSION:
7/26/10 - Disabled ncurses call for auto-color detection when CYGWIN is defined while
compiling the source code, due to a reported problem of readline failing with
ncurses in Cygwin.
7/28/10 - Disabled readline history save file for the Cygwin port,
because it is a filename that starts with a period.
7/31/10 - Added "set fractions_display" option, to allow disabling the automatic conversion of
fractions like .5 to 1/2 for display.
Developer requested and useful in the symbolic math library,
when numerical fraction output isn't wanted.
8/01/10 - Fixed a memory leak when ignoring the output string in the symbolic math library.
8/04/10 - Preserve overflowed powers like 2^2222 rather than aborting with an error message.
Allow simplification of math like 2*2^2222 and 2/2^2222.
8/08/10 - matho-primes runs twice as fast with the -ffast-math gcc compilation option,
which is now enabled by default. Don't try -ffast-math with the main Mathomatic
program though, because then Mathomatic won't work properly.
CHANGES MADE TO MATHOMATIC 15.1.4 TO BRING IT UP TO THE NEXT VERSION:
Many minor tweaks and improvements.
7/03/10 - Makefiles and compile scripts were corrected and enhanced
per http://www.gnu.org/prep/standards/
7/06/10 - Changed all "#if true" and "#if false" conditional commenting to "#if 1" and "#if 0"
in the C source code, thanks to Min Sik Kim of NetBSD pkgsrc.
CHANGES MADE TO MATHOMATIC 15.1.3 TO BRING IT UP TO THE NEXT VERSION:
All of the Unix man pages and user manuals for Mathomatic were fixed.
The compare and "solve verify" commands now simplify more thoroughly with "repeat simplify"
for better expression equality determination.
6/17/10 - Greatly improved file operation error reporting by using the perror(3) function.
6/18/10 - Fixed categories in "icons/mathomatic.desktop";
Mathomatic now goes under valid categories, mainly Education.
CHANGES MADE TO MATHOMATIC 15.1.2 TO BRING IT UP TO THE NEXT VERSION:
6/6/10 - I made mistakes in the improvement to the simplify command of version 15.1.2,
the original working simplify logic of version 15.1.1 is now restored, sorry.
CHANGES MADE TO MATHOMATIC 15.1.1 TO BRING IT UP TO THE NEXT VERSION:
A general cleanup was done.
A small improvement was made to the final result of the simplify and fraction commands.
Showing intermediate results in the calculate, sum, and product commands is now done with "set debug 1".
5/28/10 - Added "tests/collatz.in", the Collatz conjecture as an automatically computable equation.
CHANGES MADE TO MATHOMATIC 15.1.0 TO BRING IT UP TO THE NEXT VERSION:
Code and documentation cleanup.
5/21/10 - Added "primes/matho-sum", a utility that sums its command line arguments or standard input.
Use "matho-primes 0 2000000 | matho-sum" to find the sum of all primes less than 2,000,000.
Solves Project Euler problem #10: http://projecteuler.net/index.php?section=problems&id=10
5/23/10 - Primes (') are allowed in variable names now, if not using the symbolic math library, so that the
derivative, integrate, and nintegrate commands can change the dependent variable to y', y'', etc.
This can be turned on in the symbolic math library by the command "set special_variable_characters='".
Non-alphanumeric characters in variable names are now converted to underline characters (_)
when exporting to a programming language or to a different program.
CHANGES MADE TO MATHOMATIC 15.0.8 TO BRING IT UP TO THE NEXT VERSION:
5/10/10 - Added "help constants" command.
5/11/10 - Integer variables are now specified by using a variable name that starts with "integer",
like "integer1", "integer_x", etc. Currently only the modulus operator "%" checks
for integer variables, to help with simplification.
5/12/10 - Corrected the output string type of the symbolic math library API. It was erroneously declared
as type "const", possibly causing a memory leak.
5/13/10 - Moved and adapted "makefile.lib" to "lib/makefile", so the symbolic math library build is isolated.
Previously "make clean" was required between different builds. All makefiles require GNU make now.
CHANGES MADE TO MATHOMATIC 15.0.7 TO BRING IT UP TO THE NEXT VERSION:
4/26/10 - Allow "make pdf" to generate PDF documentation from the HTML documentation with htmldoc.
Please read the comments in the makefile for all available options.
4/29/10 - For every makefile, CFLAGS has been modified to include OPTFLAGS as required by the Fedora Linux
build system, and OPTFLAGS defaults to the optional gcc specific flags like optimization.
In the symbolic math library, made available the equation number of the result of calling the API,
if also stored in an equation space. The result equation number is stored in the global "result_en".
Useful if you want to know where the result was stored, to act on it with further commands.
CHANGES MADE TO MATHOMATIC 15.0.6 TO BRING IT UP TO THE NEXT VERSION:
Corrections and improvements to the documentation were made.
4/3/10 - Vastly improved the "factor number" user interface, now factors integer expressions like 2^32-1.
"factor number" is disabled in library mode.
4/13/10 - The real and imaginary commands no longer fail when the expression is not complex,
just a warning is given.
4/14/10 - Changed normal display of "-1*" to "-", for prettier 2D expression output,
so things like "-a" display properly, not as "-1*a".
CHANGES MADE TO MATHOMATIC 15.0.5:
1/28/10 - Added a Python utility called "primorial" to the Prime Number Tools install
that multiplies together the results of matho-primes, displaying the primorials
of the integers given on the command line.
3/18/10 - Changed author email address to "gesslein@linux.com".
3/23/10 - Catch SIGHUP and SIGTERM signals for proper termination of the Mathomatic program;
readline was messing up when Mathomatic was terminated by closing the shell window.
The plot command now always plots expressions with grid marks displayed for reference.
CHANGES MADE TO MATHOMATIC 15.0.4:
1/21/10 - In the makefile, changed the HTML man page generator back to rman because
groff HTML output looks really bad and rman allows linking to other man pages.
groff is no longer used.
1/24/10 - Fixed "make m4install", the installed rmath and matho programs weren't working.
1/27/10 - Added GNU LGPL license notices to every C source file with a copyright notice,
for proper protections.
CHANGES MADE TO MATHOMATIC 15.0.3:
1/9/10 - Fixed a problem only in the version 15.0.3 makefile, where it didn't respect
the CC environment variable set by the user, instead it always used "gcc"
as the C compiler.
CHANGES MADE TO MATHOMATIC 15.0.2:
12/27/09 - Moved get_screen_size() from main.c to am.c because it is used in the library when
compile-time options UNIX or CYGWIN are defined.
Thanks to Cygwin port maintainer Reini Urban for noticing and fixing this problem.
Defining UNIX or CYGWIN in library mode is not recommended.
12/31/09 - Added code to allow any command to be preceded by "repeat", which sets the
repeat flag for the following command. Most commands ignore the repeat flag.
1/1/10 - Ported divide and roots commands to be repeatable. Also repeatable are the
calculate and eliminate commands.
1/2/10 - Allow Taylor series computation even if the specified differentiation variable
is not found in the expression, giving a warning.
Ported simplify command to be a repeatable full simplify; that is, typing
"repeat simplify" repeatedly runs the simplify command until the result stabilizes
to the smallest size expression.
1/7/10 - Thanks to pretty C code submitted by Simon Geard,
the code and variables commands have been made much more readable.
1/8/10 - Made Mathomatic easier to compile under Solaris, thanks to Michael Pogue of Sun.
Fixed failure to compile under BSD Unix when compiling with readline support.
CHANGES MADE TO MATHOMATIC 15.0.1:
12/19/09 - The last few versions fix the ugliness caused by the GCD factoring change made on 6/22/09.
Today's change factors out the numerical GCD of rational coefficients as needed to simplify.
Most simplification results should be beautiful and the simplest possible again now,
without the misleading observed magnitude caused by always factoring out the GCD,
which was why the change of 6/22/09 was made.
CHANGES MADE TO MATHOMATIC 15.0.0:
12/12/09 - Fixed a problem with the -q (quiet mode) option being ignored if the session options
were ever saved with the "set save" command.
12/13/09 - Added code to allow Mathomatic output to be redirected by default.
Fixed the derivative command to be successful even when the result is 0,
when compiled as a library.
12/14/09 - Added ability to log symbolic math library results, and made command behavior
more consistent in the library by always returning the final result string.
12/16/09 - The factor command now factors more by factoring out the GCD of rational coefficients.
CHANGES MADE TO MATHOMATIC 14.6.3 TO BRING IT UP TO 15.0.0:
Cleanup and more bug fixes.
11/26/09 - Added detection of the terminal's ANSI color availability, when readline is enabled.
11/28/09 - Added detection of divide by zero and NaN when using the "solve verify" command,
for more correct results.
Solving now factors out the GCD of rational coefficients, for improved results.
The fixes today are from errors solving equations like (2*x/(x - 3)) + 3 = 6/(x - 3)
11/29/09 - Disallow the variable named "nan". NaN cannot be directly entered into Mathomatic.
11/30/09 - Added shell scripts "t" and "tests/t" to easily test Mathomatic by typing "./t".
12/2/09 - The fraction command now factors out the GCD of rational coefficients like the
solve command does, so that coefficients in algebraic fractions become integers.
The GCD verifying routine was perfected by making it very strict, like it should be.

API Changes
Returning dictionaries
Several of the algorithms and the degree() method now return dictionaries keyed
by node instead of lists. In some cases there was a with_labels keyword which is
no longer necessary. For example,
>>> G=nx.Graph()
>>> G.add_edge('a','b')
>>> G.degree() # returns dictionary of degree keyed by node
{'a': 1, 'b': 1}
Asking for the degree of a single node still returns a single number
>>> G.degree('a')
1
The following now return dictionaries by default (instead of lists) and the
with_labels keyword has been removed:
* Graph.degree(), MultiGraph.degree(), DiGraph.degree(),
DiGraph.in_degree(), DiGraph.out_degree(), MultiDiGraph.degree(),
MultiDiGraph.in_degree(), MultiDiGraph.out_degree().
* clustering(), triangles()
* node_clique_number(), number_of_cliques(), cliques_containing_node()
* eccentricity()
The following now return dictionaries by default (instead of lists)
* pagerank()
* hits()
Adding nodes
add_nodes_from now accepts (node,attrdict) two-tuples
>>> G=nx.Graph()
>>> G.add_nodes_from([(1,{'color':'red'})])
Examples
* Mayvi2 drawing
* Blockmodel
* Sampson?s monastery
* Ego graph
Bug fixes
* Support graph attributes with union, intersection, and other graph
operations
* Improve subgraph speed (and related algorithms such as
connected_components_subgraphs())
* Handle multigraphs in more operators (e.g. union)
* Handle double-quoted labels with pydot
* Normalize betweeness_centrality for undirected graphs correctly
* Normalize eigenvector_centrality by l2 norm
* read_gml() now returns multigraphs

up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after

V 4.9.5 - Dec 10, 2007 Updated software license, allowing distribution
of modified source code.
The actual library source code is identical to
version 4.9.2 (except the obvious library version
identifier, and Digital Mars #ifdef).
Added support for the Digital Mars Compiler.
Added build script for Intel Linux Compiler.
V 4.9.5a - Feb 21, 2010 Updated authors email address.
Note that there are no changes to the library
source code - so the library will still identify
itself as "4.9.5".
Added Makefile for Microsoft Visual Studio 2005.
Added another Makefile for MAC OSX (for 10.6).

Contributed by Kamel Derouiche via PR pkg/43741
Changes in this version:
It works with Borland Builder version 6, 8;
Microsoft Visual C++ 6,7,8; Open Watcom 1.7a;
Gnu version 3, 4 and Intel for Windows & Linux compilers 9, 10.
Options and work-arounds for older compilers are being removed.
You can enter values from an integer array with statements like
Matrix A(3,2); int a[] = { 11,12,21,22,31,33 }; A << a;
There is a new matrix type SquareMatrix. You can use this where
you know a matrix is square. The only place where the information
that a matrix is used is in the Kronecker product KP(A,B).
If A is band and B is any square matrix type (i.e. type SquareMatrix
or band, triangular, symmetric or diagonal) the result is band.
If B is type Matrix then the result is of type Matrix.
Apart from this it may be worth using the SquareMatrix type to
improve readability of a program and to make sure that a matrix
that is intended to be square really is square.
There is a new routine for carrying out cross products of
ColumnVectors or RowVectors of length 3 and new routines for
updating a triangular matrix derived from a Cholesky decomposition.
Interfacing with old C functions involving one and two
dimensional arrays is simplified.
Additional QR functions, extend_orthogonal function.
Lower-case versions of functions.
You can use the manipulators scientific and fixed in the matrix
output expressions.

Contributed by Stathis Kamperis on IRC.
Changes from versions 2.4.* to version 3.0.0:
- The "boudin aux pommes" release.
- MPFR 3.0.0 is binary incompatible with previous versions but (almost)
API compatible. More precisely the obsolete functions mpfr_random
and mpfr_random2 have been removed, the meaning of the return type
of the function mpfr_get_f has changed, and the return type of the
function mpfr_get_z is now int instead of void. In practice, this
should not break any existing code.
- MPFR is now distributed under the GNU Lesser General Public License
version 3 or later (LGPL v3+).
- Rounding modes GMP_RNDx are now MPFR_RNDx (GMP_RNDx kept for
compatibility).
- A new rounding mode (MPFR_RNDA) is available to round away from zero.
- The rounding mode type is now mpfr_rnd_t (as in previous versions,
both mpfr_rnd_t and mp_rnd_t are accepted, but mp_rnd_t may be
removed in the future).
- The precision type is now mpfr_prec_t (as in previous versions, both
mpfr_prec_t and mp_prec_t are accepted, but mp_prec_t may be removed
in the future) and it is now signed (it was unsigned in MPFR 2.*, but
this was not documented). In practice, this change should not affect
existing code that assumed nothing on the precision type.
- MPFR now has its own exponent type mpfr_exp_t, which is currently
the same as GMP's mp_exp_t.
- Functions mpfr_random and mpfr_random2 have been removed.
- mpfr_get_f and mpfr_get_z now return a ternary value.
- mpfr_strtofr now accepts bases from 37 to 62.
- mpfr_custom_get_mantissa was renamed to mpfr_custom_get_significand
(mpfr_custom_get_mantissa is still available via a #define).
- Functions mpfr_get_si, mpfr_get_ui, mpfr_get_sj, mpfr_get_uj,
mpfr_get_z and mpfr_get_z_2exp no longer have cases with undefined
behavior; in these cases, the behavior is now specified, and in
particular, the erange flag is set.
- New functions mpfr_buildopt_tls_p and mpfr_buildopt_decimal_p giving
information about options used at MPFR build time.
- New function mpfr_regular_p.
- New function mpfr_set_zero.
- New function mpfr_digamma.
- New function mpfr_ai (incomplete, experimental).
- New functions mpfr_set_flt and mpfr_get_flt to convert from/to the
float type.
- New function mpfr_urandom.
- New function mpfr_set_z_2exp (companion to mpfr_get_z_2exp, which
was renamed from mpfr_get_z_exp in previous versions).
- Speed improvement for large operands in the trigonometric functions
(mpfr_sin, mpfr_cos, mpfr_tan, mpfr_sin_cos): speedup of about 2.5
for 10^5 digits, of about 5 for 10^6 digits.
- Speed improvement for large operands of the inverse trigonometric
functions (arcsin, arccos, arctan): about 2 for 10^3 digits, up to
2.7 for 10^6 digits.
- Some documentation files are installed in $docdir.
- The detection of a GMP build directory (more precisely, the internal
header files of GMP) was previously done separately from the use of
the --with-gmp-build configure option. This was not consistent with
the documentation and with other parts of the configure script. So,
as of MPFR 3.0.0, the internal header files of GMP are now used if
and only if the --with-gmp-build configure option is given.
- The configure script recognizes some extra "long double" formats
(double big endian, double little endian, double-double big endian).
- MPFR manual: added "API Compatibility" section.
- Test coverage: 97.1% lines of code.
- Bug fixes.
The following suffixes for variables and constraints were
implemented in the MathProg language:
.lb (lower bound),
.ub (upper bound),
.status (status in the solution),
.val (primal value), and
.dual (dual value).
Now the MathProg language allows comment records (marked by
'#' in the very first position) in CSV data files read with the
table statements. Note that the comment records may appear only
in the beginning of a CSV data file.
The API routine glp_cpp to solve the Critical Path Problem was
added and documented.
Notable changes (compared to version 1.0.9) include:
- New domains and packages: VectorSpaceBasis domain,
DirichletRing domain, 3D graphic output in Wavefront .obj format,
specialized machine precision numeric vectors and matrices (faster
then general vectors and matrices), Html output.
- Support Clifford algebras corresponding to non-diagonal matrix,
added new operations.
- 'normalize' now tries to simplify logarithms of algebraic constants.
- New functions: Fresnel integrals, carmichaelLambda.
- Speed improvements: several polynomial operations are faster,
faster multiplication in Ore algebras, faster computation of
strong generating set for permutation groups, faster coercions.
- Several improvements to the guessing package (in particular new
option Somos for restricting attention to Somos-like
sequences
Bug fixes, in particular:
- FriCAS can now compute multiplicative inverse of a power series
with constant term not equal to 1.
- Fixed a problem with passing interpreter functions to algebra.
- Two bugs causing crashes in HyperDoc interface are fixed.
- FriCAS now ignores sign when deciding if number is prime.
- A failing coercion that used to crash FriCAS is now detected.
- 'has' test sometimes gave wrong result.
- Plotting fixes.
* R CMD INSTALL checks if dependent packages are available early on
* in the installation of source packages, thereby giving clearer
error messages.
* R CMD INSTALL --build now names the file in the format used
for Mac OS X binary files on that platform.
* BIC() in package stats4 now also works with multiple fitted models,
analogously to AIC().
* Use of file extension .C for C++ code in packages is now
deprecated: it has caused problems for some 'make's on
case-insensitive file systems (although it currently works
with the recommended toolkits).
* The C function mkCharLenCE now no longer reads past 'len' bytes
(unlikely to be a problem except in user code).
* On systems without any default LD_LIBRARY_PATH (not even
/usr/local/lib), [DY]LIB_LIBRARY_PATH is now set without a trailing colon.
* More efficient utf8ToInt() on long multi-byte strings with
many multi-byte characters.
* aggregate.ts() gave platform-depedent results due to rounding
error for ndeltat != 1.
* package.skeleton() sometimes failed to fix filenames for .R or
.Rd files to start with an alphanumeric.
(missed those and *emacs* the first time round because they pull
in their png dependencies via default-on options; they were included
in the test bulk build though)
SciPy 0.7.2 is a bug-fix release with no new features compared to 0.7.1. The
only change is that all C sources from Cython code have been regenerated with
Cython 0.12.1. This fixes the incompatibility between binaries of SciPy 0.7.1
and NumPy 1.4.
SciPy 0.7.1 is a bug-fix release with no new features compared to 0.7.0.
Based on PR#43282 by Wen Heping.
2.7.9 --> 2.7.10
----------------
Bug fixes:
- Removed all occurrences of "as" as a variable name for compatibility
with Python 2.6.
- Installation without the netCDF module did not work.
Improvements:
- Vector.dyadicProduct() was replaced by a more efficient implementation.
- Scientific.IO.PDB: Atom objects now have a parent attribute whose
value is the containing group.
2.7.8 --> 2.7.9
---------------
License change: ScientificPython is now distributed under the
CeCILL-C license, which is an adaptation of the LGPL to French
law. The previously used CeCILL license, similar to the GPL, was
considered too restrictive.
Bug fixes:
- MPI interfaces did not work correctly with NumPy and/or Python 2.5.
Improvements:
- Compilation script for mpipython works around a Python configuration
bug under MacOS X.
- Docstrings have been cleaned up.
2.7.7 --> 2.7.8
---------------
Bug fixes:
- Due to a typo in Scientific.IO.PDBSpaceGroups, some space group
names were not found in the space group table.
Improvements:
- Vector objects can now be multiplied with NumPy scalar objects
(which is what you get when extracting numbers from NumPy
arrays). Due to the way NumPy scalars handle multiplication, the
result used to be an array rather than a Vector, which caused
various applications to crash.
- The build procedure under Windows has been improved. It can
generate a binary installer that includes the netCDF DLL,
making ScientificPython independent of a netCDF installation.
2.7.6 --> 2.7.7
---------------
Bug fixes:
- Installation on Windows didn't work because the Unix maths libraries
don't exist there.
Improvements:
- InterpolatingFunction and TensorField objects can represent
periodic functions/fields.
- DistributedComputing: the watchdog period of slave processes is now
a user-definable parameter.
- PDBSpaceGroups was simplified, making it shorter and faster to load.
- Scientific.N contains the array type object in the variable array_type.
This makes it possible to write Pyrex modules using arrays in such a
way that they always use the numeric module for which ScientificPython
was compiled.
2.7.5 --> 2.7.6
---------------
Bug fixes:
- NumPy compatibility fixes.
- Pyro 3.6 compatibility fix in DistributedComputing.MasterSlave
2.7.4 --> 2.7.5
---------------
New features:
- Scaling, inversion, and shear transformations added to
Geometry.Transformations
Improvements:
- PDB parser handles CRYST1, SCALEn and MTRIXn records
- Better identification of the Numerics package that is being used
Bug fixes:
- Scientific_affinitypropagation.c compiles with NumPy
2.7.3 --> 2.7.4
---------------
New features:
- New module Clustering.AffinityPropagation.
- New class BSP.ParRootSequence.
Bug fixes:
- Replaced float equality test in Functions.InterpolatingFunction
- Removed exception for order > 1 in Derivatives.DerivVar.__init__
- Fixed reading of non-string attributes from netCDF files.
Improvements:
- New methods getBinIndices and getBinCount in Statistics.Histogram.Histogram
- Physics.PhysicalQuantities: unit definitions added to doc string
2.7.2 --> 2.7.3
---------------
Improvements:
- Added multi-module setup for master-slave computations.
- More information available through task_manager.
- task_manager can start slave processes.
2.7.1 --> 2.7.2
---------------
Bug fixes:
- Scientific_netcdf would not compile with NumPy under Python 2.4
because NumPy also defined Py_ssize_t.
2.7 --> 2.7.1
-------------
Improvements:
- NumPy compatibility. Scientific_netcdf was revised by hand.
The Python code was run through numpy.oldnumeric.alter_code1 to
identify the critical sections, which were then all handled in
some way. It is possible that there are still incompatibilities
of the kind that numpy.oldnumeric.alter_code1 cannot detect
2.5.12hg --> 2.7
----------------
New features:
- Subpackage Scientific.DistributedComputing for easy parallelization
of independent tasks.
2.5.11 --> 2.5.12hg
-------------------
Bug fixes:
- VRML2 output would crash for scenes containing Line objects
- Pyrex implmentation of vector objects could crash instead of raising
an exception in divide operations.
- Pyrex implmentation of vector objects would raise exceptions incorrectly
under Python 2.5
Improvements:
- builds Macintosh packages with documentation and examples
2.5.10 --> 2.5.11
-----------------
Bug fixes:
- Pyrex implementation of vector objects raised exceptions in comparisons
- Pyrex implementation of vector objects did not accept negative indices
- Some object deletions during conversion to epydoc had to be reversed
Improvements:
- Two test suites
2.5.9 --> 2.5.10
----------------
Bug fixes:
- Fixed netCDF error handling
Improvements:
- Support for NumPy (not very well tested yet)
- Scientific.NumberDict more efficient
2.5.8 --> 2.5.9
---------------
Improvements:
- Scientifc.IO.NetCDF supports the new 64-bit data structures in Python 2.5
(not yet tested on a 64-bit machine)
- Docstrings modified for use with Epydoc.
2.5.7 --> 2.5.8
---------------
Bug fixes:
- Syntax error in Scientific.IO.PDB
- Attribute deletion in netCDF file and variable objects caused a crash.
2.5.6 --> 2.5.7
----------------
Bug fixes:
- Tensor-vector multiplication was incorrect with the Pyrex implementation
of vector objects.
2.5.5 --> 2.5.6
----------------
Bug fixes:
- Scientific.BSP.ParClass did not pass on __call__ and __getitem__
to local class
- Scientific.BSP.ParClass: Class wrappers did not always return the right
global object.
2.5.4 --> 2.5.5
----------------
Bug fixes:
- Scientific.IO.NetCDF.NetCDFVariable.assignValue() had incomplete error
reporting. Some errors would not raise exceptions as required.
2.5.3 --> 2.5.4
----------------
Improvements:
- A "test" method on MPI request objects permits to check if data
is available (thanks to Jakob Schiotz for this addition).
Bug fixes:
- The new Pyrex vector objects could not be pickled.
2.5.1 --> 2.5.3
----------------
Improvements:
- The class Scientific.Geometry.Vector has been reimplemented in Pyrex,
yielding much faster vector operations. There is, however, the restriction
that the vector elements must be of type "float". For the rare applications
where this condition is not fulfilled (such as
Scientific.Functions.Derivatives.DerivVector), the Python implementation
remains accessible as Scientific.Geometry.VectorModule.Vector.
2.4.9 --> 2.5.1
----------------
Improvements:
- Vector and Tensor objects permit comparison with other types
of objects (which always return False)
- Numarray can be used instead of Numeric as far as possible
(see README for details)
2.4.7 --> 2.4.9:
----------------
Bug fixes:
- Integer array attributes caused a TypeError with recent versions of
Numeric (that don't do silent casts from Long to Int any more).
Additions:
- Method "threeAngles" in Geometry.Transformation.Rotation.
2.4.6 --> 2.4.7:
----------------
Bug fixes:
- Scientific.BSP: alltrue() and anytrue() sometimes returned wrong results.
Additions:
- Scientific.Visualization.VMD can now correctly launch VMD under Windows
* This is a maintainer release.
* `configure.ac' was changed to allow building the package under

TinySVM is an implementation of Support Vector Machines (SVMs) [Vapnik 95],
[Vapnik 98] for the problem of pattern recognition. Support Vector Machines is a
new generation learning algorithms based on recent advances in statistical
learning theory, and applied to large number of real-world applications, such as
text categorization, hand-written character recognition.
* To compile fityk, Boost (only headers) and xylib must be installed first.
Fityk tarball does not contain a copy of boost and xylib now.
* user-defined functions: split functions can be defined in this way:
SplitG(h, c, w1, w2) = x < c ? Gaussian(h, c, w1) : Gaussian(h, c, w2)
* added info-numeric-format option
* a couple of bug fixes
Changes 0.9.1:
* added cfityk to Windows installer
* Unix only: fitting can be interrupted by the INT signal
* changed output of "info errors", see the manual for details
* GUI: "plot in @n" changes selected datasets (useful in scripts)

More...
besides being portable and extensible, for instance three dimensional
tables and iterative expressions.
The most important feature is the funktional addressing of cells,
unlike the traditional approach like A0, C5, etc. which is probably
inherited from VisiCalc.
From Wen Heping in PR pkg/43204.
This minor release removes datetime support, which fixes the binary
incompatibility issues with SciPy and other packages. It also includes several
bug fixes. No new features are introduced.

C++ library of mathematical, signal processing and communication
routines
Its main use is in simulation of communication systems and for
performing research in the area of communications. The kernel of the
library consists of generic vector and matrix classes, and a set of
accompanying routines. Such a kernel makes IT++ similar to MATLAB or
GNU Octave.
* What is new in gsl-1.14:
** Upgraded to latest libtool, autoconf and automake (libtool-2.2.6b,
autoconf-2.65, automake-1.11.1). Fixes security hole in 'make
dist' (see Automake CVE-2009-4029).
** Added support for "multisets", which are similar to permutations
and combinations. A multiset is an array of k integers in the
range 0 to n-1 where each value may occur more than once. Multisets
can be used to iterate over the indices of a k-th order symmetric
tensor in n-space. (Rhys Ulerich)
** Added gsl_integrate_glfixed routines for performing fixed order
Gauss-Legendre integration
(Pavel Holoborodko, Konstantin Holoborodko, Rhys Ulerich)
** In the LMDER multi-dimensional fitting routines, the return code
GSL_ENOPROG is now used instead of GSL_CONTINUE for the case where
10 or more attempts to find a suitable trial step have been made
without success. [bug #25383]
** The confluent hypergeometric function gsl_sf_hyperg_U (a,b,x) has
been extended to support x < 0 for cases not involving
singularities in 1F1(a,b,x). [bug #27859]
** The F-distribution gsl_ran_fdist_pdf now avoids unnecessary
underflow and overflow and handles cases where n > 248. [bug
#28500]
** The SVD routines now use a scaled version of the implicit QR method
and compute the shift more reliably for values at the limit of
double precision, avoiding potential NaNs. [bug #28767]
** A compile time error is emitted if the configuration stage prevents
the functions gsl_isnan and gsl_finite from being defined.
** Added missing dereference in GSL_VECTOR_COMPLEX when not using
GSL_RANGE_CHECK [bug #28017]
** Improved the range of gsl_sf_hyperg1F1(a,b,x) when a<0,b>0. [bug
#28718]
** Added macros GSL_MAJOR_VERSION and GSL_MINOR_VERSION in
<gsl/gsl_version.h>
** Improved gsl_eigen_symmv and gsl_eigen_symm to avoid a potential
infinite loop when the tridiagonalised matrix contains very small
values. [bug #28096]
** Added functions gsl_multifit_linear_usvd and
gsl_multifit_wlinear_usvd for multilinear fitting without
column-scaling of the fit matrix.

changes:
-Fix negative exponential detection
-Only disable trailing zeroes option in basic mode
-Disable ambiguous multiplication with Eulers number, e.g. "2e" as this
makes exponential numbers confusing
Changes since previous release:
Compiler
- The compiler now treats ^ as alias for **.
- The compiler now rejects ambiguous left hand sides of
definitions where parameter types are left out for
inference. Previously, the compiler would pick the first
signature from some mostly random order, with a warning.
- For categories with default implementations, the compiler
can be directed to compile only the purely category part
(exports), or only the default implementations (category
packages).
- The compiler now supports a Foreign Function Interface. In
particular, signatures for external entities may be declared
at capsule level. Currently, only ISO C functions are
supported, but future releases may support ISO C++ and other
mainstream languages.
- The parsing of signature for operators has been improved.
Previously, operator names needed to be quoted in signature.
That is not longer needed. For instance, previously, one had
to write (at category level)
"*": (%,%) -> %
_/_\: (%,%) -> %
_not: % -> %
With this release of OpenAxiom and onward, one can simply write
*: (%,%) -> %
/\: (%,%) -> %
not: % -> %
which is much simpler to read, write, and much more regular.
- The compiler now supports is-case pattern matching. The new
pattern matching syntax is useful for structuring retractions,
and also for domain recovery from expressions of type Any.
- The compiler now supports the loop control transfer operator
iterate in repeat loops - previously, the construct was
accepted only in scripts (not libraries). That discrepency is
now ended.
Interpreter
- Declared variable with no specified values are now handled
as if symbolic value with a specified type.
- The interpreter now parses a disjunctive expression
involving the 'is' operator the obvious way. E.g. Now
T is Integer or T has Ring
is now understood as
(T is Integer) or (T has Ring)
- The interpreter now handles existentially quantified or
universally quantified expressions
Algebra
The following types have been added to OpenAxiom-1.3.0
- The domain Boolean and category BitAggregate no longer
export the operation ^ for logical negation. Use the
operator not which is the canonical and documented operator.
- The domain InputForm now has a new exported signature
parseString: String -> %
for parsing expressions given as string.
- The domain Boolean now belongs to the category
OrderedFinite.
- The domain KleeneTrivalentLogic is added. It implements
Stephen Kleene's 3-valued propositional logic.
- For file orinted I/O, new domains have been added:
+ IOMode: This domains defines three constants to indicate
the direction of file I/O operations.
+ InputBinaryFile: This domains implements the basic input
operations on binary files.
+ OutputBinaryFile: This domains implements the basic
output operations on binary files.
- The domain BinaryFile has been replaced by three specific domains:
+ InputBinaryFile: datatype for input file open in binary mode;
+ OutputBinaryFile: datatype for output file open in binary mode;
+ InputOutputBinaryFile: datatype for input and output file open
in binary mode.
- Three new categories are introduced, related to conversions:
+ CoercibleFrom: This category is the mirror image of the
standard category CoercibleTo.
+ HomotopicTo: This category is the symmetrization of the
category CoercibleTo.
+ ConvertibleFrom: This category is the mirror image of
ConvertibleTo.
- Previous releases defined instantiations of the domain
constructor Expression as satisfying the category OrderedSet.
That was both confusing and incorrect in conjunction with
other algebraic structures. From now on, Expression(T) no
longer satisfies OrderedSet.
- Three new categories have been added:
+ LeftLinearSet
+ RightLinearSet
+ LinearSet
The category AbelianGroup extends LeftLinearSet Integer.
The parameterized category constructor LeftModule extends
LeftLinearSet. Similarly, the category RightModule extends
RightLinearSet.
- The domain Any has been reworked. In particular, the
operation domainOf, objectOf, and showTypeInOutput have been
removed. Equality of two objects of domain Any is equality
according to the underlying domain, if that domain belongs to
the category BasicType; otherwise, it is equality of storage
locations.
Runtime System
The Lisp backend now uses type information derived from exports
and domain representation for code generation purposes.
Notable changes (compared to version 1.0.7) include:
- Improved version of guessing package. It can now handle
much larger problems than before. Added ability to guess
functional substitution (Mahler) equations.
- Experimental support for build using CMU CL.
- Various speed improvements including faster indexing for two
dimensional arrays.
- By default FriCAS build tries to use SBCL.
- Building no longer require patch.
Bug fixes, in particular:
- correct definition of random() for matrices
- conditionals in .input files work again
- Spad compiler now recognizes more types as equal
- fixed problem with pattern-matching quote
Changes from version 2.4.1 to version 2.4.2:
- Security fix in formatted output functions (buffer overflow).
- Formatted output functions: 6 is now the default value for
empty precision field with %Rf.
- Better portability of configure script.
- Detection of intmax_t and uintmax_t types.
- Improved documentation: mpfr_get_z_exp, mpfr_strtofr, mpfr_get_str and
formatted output functions.
- Improved message in case of assertion failure.
- Test coverage: 97.0% lines of code.
- Updated tcmp_ld test to really test the long double.
- Some documentation files are installed in $docdir.
- Removed mpfr_init_cache (unused and undocumented function).
- Fixed the way $CC / $CFLAGS are got from gmp.h (__GMP_CC / __GMP_CFLAGS).
- Bug fixes.
- Also note that GCC 4.4.0 (only this obsolete version) does not build
MPFR 2.4.2 correctly; this is detected by "make check" (failures in
tget_z and tpow_all).
