- bug fix in handling of -pi (previous version changed constant pi)
- bug fix in division of integer vectors with negative coefficients
- for loop can now handle >= 2**32 iterations
- fixed bug which occurred in V 1.50 while parsing certain
parenthized expressions
Changes:
Some more improvement to simplification.
Displayed floating point precision reduced to 12 digits.
Allow typing just "e#" or "pi" on the command line, to give the
values for each.
Changed simplify command to prefer (1/constant)^n instead of 1/(constant^n).
It produces more efficient code and solves a problem.
Improved "code integer" command by allowing integer powers.
Improved eliminate command by trying next equation if solve fails.
"list export" now produces 100% Maxima compatible equations.
Changed "SILENT" compile time define to also remove all debugging code.
Core simplex method and interior-point method routines were
re-implemented and now they use a new, "storage-by-rows" sparse
matrix format (unlike previous versions where linked lists were
used to represent sparse matrices). For details see ChangeLog.
Also a minor bug was fixed in API routine lpx_read_cpxlp.
* Added a new wavelet directory, with 1-dimensional and 2-dimensional
discrete wavelet transforms.
* Added support for LQ and P^T LQ decompositions. To find the QR
decomposition of large systems (M>>N) use the LQ decomposition,
solving the transpose of the original system. This allows more
efficient memory access, and is useful for solving large least-squares
problems.
* Fixed a bug in the SYRK and HERK blas functions gsl_blas_{s,d,c,z}syrk
and gsl_blas_{c,z}herk which caused invalid memory access for non-square
matrices.
* Fixed a bug in gsl_swap_vectors which caused it to return incorrect
results when swapping vectors with different strides.
* Corrected the error estimate for gsl_cheb_eval_n_err to use
evaluation order instead of the approximation order.
* Improved the reliability of the gsl_sf_gamma_inc family of
functions.
* Equal abscissae are now handled gracefully in the cspline and
periodic cspline interpolations.
* Removed potential cancellation error in calculation of uniform
histogram ranges.
* Improved numerical stability of integration for akima and cspline
interpolation.
* Differential equation solvers now handle error codes returned from
user-defined functions.
* Improved error estimates in ode-initval solvers, and provide exact
derivatives on output. Added new semi-implicit ode-initval solver,
gsl_odeiv_step_rk2simp.
* Added missing function definition for gsl_sf_psi_1.
* Fixed the function gsl_sf_expint_Ei_scaled to call
gsl_sf_expint_Ei_scaled_e instead of gsl_sf_expint_Ei_e.
* Added cumulative distribution function for exponential power
distribution.
* The functions gsl_cdf_beta_P and gsl_cdf_beta_Q now return
consistent results of 0 or 1 for out of range values, x<0 and x>1,
rather than 0 for left and right tails simultaneously.
* The Jacobi eigensolvers gsl_eigen_jacobi and gsl_eigen_jacobi_invert
have new implementations from Golub and Van Loan.
* The standard output and standard error streams are now flushed by
the default error handler before the program aborts, in order to
ensure that error messages are properly displayed on some platforms.
post-configure time, even after the switch from buildlink2 to buildlink3.
Also, use SUBST_CLASSES instead of the custom post-configure target,
and take advantage of the fact that the "unwrap" SUBST_CLASS already
does mostly the right thing.
Overview of changes in gcalctool 4.4.22
* Fixed bug #163468. Pressing "(<Del>)" would cause gcalctool to crash.
Overview of changes in gcalctool 4.4.21
* Fixed bug #157277. Entering "(" followed by Clr using the mouse to
click on the buttons, caused a bogus character to be displayed and
the display wasn't cleared.
framework. The list of changes include:
* Modify compiler.mk so that "c" is always prepended to USE_LANGUAGES,
so we no longer need to say it in package Makefiles. Packages
should now append to USE_LANGUAGES instead of setting it.
* Create mk/compiler/f2c.mk which implements another pseudo-compiler
"f2c" that may be used with any C compiler backend, e.g.
PKGSRC_COMPILER= f2c ccache gcc
* Teach the various "real" compiler files, e.g., sunpro.mk, mipspro.mk,
etc., to use f2c if the native Fortran compiler isn't present.
Packages that use Fortran should now simply include the line:
USE_LANGUAGES+= fortran
in the package Makefile.
Changes:
- Some more touch-ups to solve routine.
- Changed uf_repeat() to skip expanding if the expression would be too big.
This allows Mathomatic to work with huge exponents.
- Turned on "preserve_roots" option by default.
- Improved sum and product commands. Allow counting down.
- Improved solve routine and removed display of useless messages.
- Added a fix to the limit command.
- Moved "source.txt" into "README.txt".
- Added code to simplify (inf+a) to (inf) generally.
- Fixed minor bug in calculate command.
- Minor fixes to elim_k().
- Improved limit command.
- Made all recursive functions in the source code static.
Most functions never used globally defined as static.
- Improvement in command argument parsing.
- Added extrema command.
- Improved output of roots command.
- Fixed minor bug caused by "preserve_roots" option.
- Made file "am.htm" valid HTML.
- Simplification improved.

This module generates a variety of random numbers. Capabilities of wide
interest include the generation of:
. uniform numbers between 0 and 1 (or user chosen boundaries)
. random integers between user specified bounds
. random permutations of a list (shuffle a deck of cards)
Changes:
- Many minor improvements made, none of which are worth mentioning by
themselves.
- Fixed all message strings with a variable listed in them.
- Added iteration option to calculate command.
- Trimmed set command of fat. Unnecessary messages removed.
- Removed all occurrences of "usage_flag".
- Usage info is now displayed everytime a command returns with error.
- Allow parsing of hexadecimal constants. Preceed hex numbers with
"0x".
- There may be parsing bugs. Systems using older versions of the GNU
libraries (specifically strtod(3)) will not allow hexadecimal input.
- Added limit command.
- Trapped 0^(negative number). It previously produced junk.
- Allow solve routine to produce infinity as an answer.
- Some commenting and fixing done to solve routine.
Fixed a bug reported by the sourceforge user: cedars where:
ln(exp(6)) == 3 /* WRONG!!! */
incorrectly returned 1. This bug was fixed by Ernest Bowen
The regression test was expanded to cover this issue.
Added minor improvements to hash regression testing of pi().
Fixed "help script" and the calc man page regarding the requirement
of -f to be the last -flag in shell script mode. Further clarified
the meaning and placement of the -f flag.
Moved issues with chi.cal intfile.cal into a "mis-features" section
of the BUGS file. See "help bugs" or the BUGS source file for details.
Added the bug about:
calc 'read ellip; efactor(13*17*19)'
to the BUGS file. See "help bugs" or the BUGS source file for details.
Anyone want to track down and fix this bug?
We might replace the gnumeric-1.2.x pkg eventually. Can't do this now
because the Python plugin isn't built for some reason, so this would
be a regression. (Don't have time to fix this right now.)
module directory has changed (eg. "darwin-2level" vs.
"darwin-thread-multi-2level").
binary packages of perl modules need to be distinguishable between
being built against threaded perl and unthreaded perl, so bump the
PKGREVISION of all perl module packages and introduce
BUILDLINK_RECOMMENDED for perl as perl>=5.8.5nb5 so the correct
dependencies are registered and the binary packages are distinct.
addresses PR pkg/28619 from H. Todd Fujinaka.
Changes:
- Added loading of $HOME/.mathomaticrc on startup.
Set options go there.
- Added undocumented switch "-t" which sets test mode.
Only used with "make test".
- Wrote and added "matho-pascal" program to primes directory.
- Allow "=" in set command.
- Improved uf_repeat() and modulus simplification.
Now GLPK supports free MPS format. Two new API routines
lpx_read_freemps (to read problem data in free MPS format) and
lpx_write_freemps (to write problem data in free MPS format)
were added. This feature is also available in the solver glpsol
via new command-line options --freemps and --wfreemps. For more
details see the GLPK reference manual.
API routines lpx_read_cpxlp and lpx_write_cpxlp for reading and
writing problem data in CPLEX LP format were re-implemented to
allow long symbolic names (up to 255 characters).
The following three modules were temporarily removed from the
GLPK distribution due to licensing problems: DELI (an interface
module to Delphi), GLPKMEX (an interface module to Matlab), and
JNI (an interface module to Java).
Algorithmic changes
* Input of numbers in bases 2, 4, 8, 16 and 32 is now done in linear bit
complexity as opposed to O(N^2). Useful for all kinds of persistency.
Implementation changes
* Fixed several bugs in the integer input and output routines that could be
blamed for random crashes in the following cases: output in base 32 for
quite large numbers, input in base 2 for fixnums and input in base 3 for
fixnums on a 64 bit target.
* Fixed crash when radix specifiers were used in input streams.
* Speed up on x86_64 and ia64 by adding some inline assembly.
Other changes
* Fixes for compilation on MacOS X and little endian Mips.

check if complex_householder_hv is available
check for Cygwin
faster MonteCarlo implementation
more and renamed constants (MKS -> MKSA, CGS -> CGSM)
better (meaning more sensible) error handling
fixed initialization bug in Spline
more samples
* Only use unicode character if available in the used font
Fixes plus sign not displayed correctly in keypad, and wide keypad
* Do not round exact integers not in exponential format.
Fixes display of large numbers in non-decimal number bases * Fix crash on systems, such as amd64, where size_t is not long int
* Do not update plot data when not changed
* Rearrange plot dialog and make x variable separate for each plot
function

option to set default angle unit to none, to allow angle unit in argument
* Try with assumptions set to unknown in solve function if not successful
* Be more picky in comparisons with units
* Fix comparison of unit with unknown
* Fix 0.5!
script. This is needed if you want to use mkoctfile once the package is
installed. For example, on NetBSD-1.6* systems, it is important to point
to the gcc3 package tools instead of the base system compilers.
It is small and simple to use but with much power and versatility underneath.
Features include customizable functions, units, arbitrary precision, plotting,
and a graphical interface (GTK+) that uses a one-line fault-tolerant expression
entry (although it supports optional traditional buttons).
Changes 2.0.1:
This is a maintenance version mainly to fix a number of minor bugs and
issues. Some rather nasty bugs were Windows-specific.
Changes 2.0.0:
Many things have changed since 1.0. The R language has acquired namespaces,
exception handling constructs, formal methods and classes, much improved
garbage collection, generalized I/O via connection objects, and
considerable improvements in the graphics area. The user workspace has been
reorganized, and so has the set of packages that ship with R. Several
"recommended packages" deemed indispensable in a statistical system are
bundled. In addition, there has been a large number of more specific new
functions, tweaks, and bugfixes.
Changes:
- Using "memmove()" instead of deprecated "bcopy()".
- Added "tests/tutor.in", which is an incomplete Mathomatic tutor.
- Many improvements to scripts in the tests directory.
- Removed "calculate factor" option.
- Code cleanup.
- Added more modulus simplification.
- Simplify ((a%n)*integer+b)%n to (a*integer+b)%n generally and completely.
- real^complex and complex^complex are now approximated.
Changes:
- Removed obsolete short variable name code and bumped up "MAX_VARS" to 500.
- Fixed problem with conflicting names and code for "cpow()" and "cexp()".
Renamed to "complex_pow()" and "complex_exp()".
Unfortunately, guile{,14}/buildlink3.mk directly includes it, and I don't
know which dependencies actually need libltdl, so it was a recursive bump.
Hopefully this recursive inclusion can be ripped out of
guile{,14}/buildlink3.mk at some point and bubble down to dependencies that
actually use libltdl, avoiding this headache in the future....
Changes:
- Added "code integer" command, which outputs working C code with integer
variables.
- Changed makefile to use libncurses instead of libcurses.
- Added more simplification rules for modulus.
as it's only used internally by bsd.prefs.mk.
* Make _PKGSRCDIR a public variable by renaming it to PKGSRCDIR.
Also, generate its value from ${_PKGSRC_TOPDIR} so it's less fragile
than the old method of stripping off the last two components of
${.CURDIR}. PKGSRCDIR may now be used after bsd.prefs.mk is defined.
* Change all references to _PKGSRCDIR to PKGSRCDIR.
Changes:
Changed sum and product commands to not create another equation if the
result is a constant. If the result is a constant, it is just displayed.
Mathomatic now approximates -1^(2^.5) and the like.
Added modulus (%) operator.
Added simplification of univariate modulus expressions.
Changed univariate modulus simplification to multivariate, integer only
simplification.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
v4.1
COSMETIC/USABILITY IMPROVEMENTS
- The File->Description dialog now updates automatically if you leave it open
while loading a new pattern file. Also, any previous description dialog is
closed when you open a new one.
- GtkLife now issues a warning dialog if it appears the application was not
propery installed (i.e., "make" without "make install").
- GtkLife now issues a warning dialog if the configured pattern collection
is not found.
BUG FIXES
- Fixed a bug that prevents the start/stop button from changing color when
Gtk+ has debugging enabled (thanks to James Gregory for reporting).
- Fixed stair-stepping effect when drawing diagonal lines.
MISCELLANEOUS
- Better ChangeLog :-)
v4.0
NEW FUNCTIONALITY
- The world size has been bumped up to 1 million x 1 million.
- Added View->Find Active Cells, to locate a live (and preferably active)
region and center on it.
- gtklife has a new default file format, GLF, which is similar to RLE.
- gtklife can now handle multiple file formats: Life 1.05 (the original
format), Life 1.06, RLE, XLife, and GLF. File type is auto-detected when
loading. Information on file formats was added to the "File Handling"
section of the documentation, and a page was added giving detailed
information on the GLF format.
- You can now set a per-session pattern directory
(File->Change Pattern Collection) as well as a default pattern directory
(Preferences/File/Default Pattern Collection).
- Sidebar patterns can now be bundled into sub-directories. Directories will
be displayed with trailing slashes. Click on a directory name to display
its contents in a clickable list beneath the sidebar.
- You can now specify a pattern collection directory on the command line
(previously only individual patterns could be loaded via command line).
- The pattern description has been made unbounded in length and width. An
error will occur if you attempt to save a pattern with a too-large
description to a LIF or RLE pattern file.
COSMETIC/USABILITY IMPROVEMENTS
- Mouse wheel over the description text box now scrolls the description
(previously you had to hover the mouse over the scrollbar).
- The color picker in Preferences now uses the contents (if any) of the
corresponding text entry as its starting color.
- Recent files in the File menu now display full path as a tooltip.
- Sidebar scrollbar is now only displayed when needed.
PATTERN COLLECTION CHANGES
- A new pattern collection, JSLife by Jason Summers, is now available as an
option. The sidebar can be set to display the original LifeP, JSLife, or
a custom collection of your own.
- Patterns were reorganized into a hierarchical format.
- Patterns were renamed to be more human-readable.
- Patterns were converted to GLF for speed of loading.
- Pattern descriptions were reformatted.
- Paul Rendell's Turing Machine pattern was added to the LifeP collection.
- Added a longer description to the Unit Cell pattern.
- Now that we have a command to locate active cells, re-centered the Jaws
pattern.
- Note: Due to a minor change in the config file, any custom pattern
directory that you have chosen previously will be reset.
DOCUMENTATION IMPROVEMENTS
- Fixed broken link to the Scientific American article in help.
MISCELLANEOUS
- The install process now deletes any existing patterns bundle before copying
over the new patterns.
- Added new nifty program icons based on the "pulsar".
Changes since 11.3c:
Improved eliminate command error handling.
Added "eliminate all" command.
Code cleanup.
Man pages for the prime number tools were contributed
by David Moreno Garza. Many thanks.
Renamed the Mathomatic directory in the source tarball to
"mathomatic-`cat VERSION`".
Added several comments to the source code.
Renamed prime number tools to "matho-*".
Improvement to full simplification.
Tried something new with uf_simp() that fixed a problem with Mathomatic
solve complicating expressions.
Minor bugfix to eliminate command.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
This release adds changes to better support compiling under cygwin,
improved custom function support, including the addition of the
pmodm127 example and config("compile_custom") and config("allow_custom")
calls, and a missing display help file. It fixes configuration
state hashing, document typos, calc -d (to disable printing of the
leading ~), and some compilation warnings reported under OS X.
installed files.
- libtoolize a few more lines which seem to have been missed in the original
libtoolization.
- enable loading of shared objects which lets the various .oct files installed
by octave-forge actually work instead of just the .m files.
which are the full option names used to set rpath directives for the
linker and the compiler, respectively. In places were we are invoking
the linker, use "${LINKER_RPATH_FLAG} <path>", where the space is
inserted in case the flag is a word, e.g. -rpath. The default values
of *_RPATH_FLAG are set by the compiler/*.mk files, depending on the
compiler that you use. They may be overridden on a ${OPSYS}-specific
basis by setting _OPSYS_LINKER_RPATH_FLAG and _OPSYS_COMPILER_RPATH_FLAG,
respectively. Garbage-collect _OPSYS_RPATH_NAME and _COMPILER_LD_FLAG.
The octave-forge project contains functions for Octave which are not in
the main distribution. While the main Octave distribution is
conservative about accepting new functions and changes, octave-forge is
very open. As a result, be prepared for some lower quality code and
more rapidly changing interfaces to the functions in octave-forge.
notable changes besides bugfixes are:
** Multifit routines now handle iterations where |f| is already
minimised to zero, without division by zero.
** Numerical derivatives should now be calculated using the
gsl_deriv_forward, gsl_deriv_central and gsl_deriv_backward functions,
which accept a step-size argument in addition to the position x. The
original gsl_diff functions (without the step-size) are deprecated.
** The tridiagonal matrix solvers gsl_linalg_solve_symm_tridiag,
gsl_linalg_solve_tridiag, gsl_linalg_solve_symm_cyc_tridiag,
gsl_linalg_solve_cyc_tridiag now use the GSL_ERROR macro to report
errors, instead of simply returning an error code. The arguments to
these functions must now use exact lengths with no additional
elements. For cyclic systems all vectors must be of length N, for
tridiagonal systems the offdiagonal elements must be of length N-1.
** The singular value decomposition routines gsl_linalg_SV_decomp and
gsl_linalg_SV_decomp_mod now handle the SVD of a column vector (N=1,
arbitrary M), which can occur in linear fitting.
** Added Stefan-Boltzmann constant and Thomson cross section to
physical constants
Changes:
"factor number" command now accepts more than one integer.
Added file "mathomatic.ico".
Added temporary fix for 64 bit longs.
Added file "VERSION" which contains the version number of Mathomatic.
"makefile" modified.
Renamed "lgpl.txt" to "LICENSE.txt".
"make install" now installs all HTML files in "/usr/local/doc/mathomatic".
Added compile-time define "TIMEOUT_SECONDS".
Useful for limiting the amount of time Mathomatic can run as a CGI.
LibTomMath provides highly optimized and portable routines for a
vast majority of integer based number theoretic applications
(including public key cryptography). LibTomMath is not a cryptographic
toolkit itself but it can be used to write one [Used in LibTomCrypt
for RSA, DH and ECC public key routines].
Changes:
Proper exit after error reading files on the command line.
Added code to preserve roots of integers, if the result is irrational.
Fixed "calculate >filename".
Made "+/-2^.5" work as expected.
Code cleanup.
Full simplify added for every loop of taylor command.
Removed "replace temp" option, so that the "temp" variable can be renamed.

Changes:
Substantial change/improvement to simplify command.
Added some more code to fix floating point inaccuracies.
Improved solving. y=(x+1/x)^3 solves both ways, now.
Full simplify after every loop in derivative command added.
Move derivative and taylor commands to "diff.c".
Added "-m" option to Mathomatic (memory size multiplier).
It sets the size of equation spaces at run time.
important changes:
- Ports of Numeric functions
A bunch of Numeric functions were ported to numarray in the new
libnumeric module. To get these import from numarray.numeric. Most
notable among these are put, putmask, take, argmin, and argmax. Also
added were sort, argsort, concatenate, repeat and resize. These are
independent ports/implementations in C done for the purpose of best
Numeric compatibility and small array performance. The numarray
versions, which handle additional cases, still exist and are the
default in numarray proper.
- Faster matrix multiply
The setup for numarray's matrix multiply was moved into C-code. This
makes it faster for small matrices.
- bug fixes
For a complete list of changes see:
http://sourceforge.net/project/shownotes.php?release_id=250453
# XXX: following comment still true for buildlink3?
# R does ugly things in the configure to get the default list of arguments
# for linking Fortran, which exposes the buildlink2 tricks so clean up
# afterwards
Changes:
Renamed the Mathomatic executable to "mathomatic".
Add inverse Laplace transform. Usage: laplace inverse x
Fixed bug in solving for zero, which occurred when there were no
variables in the divisor.
Some improvement in solve routine.
This only worked with gnumeric-1.0.x, and depends on gnome1 structures.
gnumeric is at 1.2.x now, uses gnome2 and comes with an own plotting
package.
Should fix PR pkg/26009 by MLH.
This release fixes a bug related to post incrementing, some regression failures related to compiling under cygwin, and a number of gcc compiler warnings.
Changes:
Slight improvement to integrate and laplace commands.
Integrate/laplace x on (a+x)/(b+c) works now.
Added more examples to the documentation (am.htm).
2 to 10 times speedup for simplify command by fixing polynomial factoring.
The primary purpose of this release is to correct problems on big-endian
64 bit platforms. It also introduces some test code to verify that the
functions and constants work properly.
Changes since 11.2:
Doubled the default amount of memory consumption to 11 megabytes.
This allows equations twice as large.
Fixed bug factoring infinity.
Slight improvement to "integrate" command.
Trap window resize signal and set number of screen columns and rows.
Code cleanup.
Fixed factoring of constants in factor command.

Improvement and speedup for poly_gcd() and poly2_gcd().
Slight improvement in polynomial factoring made by deleting 1 line of code.
Use getopt(3) to parse command line options.
Made "-c" and "-h" options work together. If both are specified,
work in HTML mono mode.
CHANGES IN R VERSION 1.9.1
NEW FEATURES
o as.Date() now has a method for "POSIXlt" objects.
o mean() has a method for "difftime" objects and so summary()
works for such objects.
o legend() has a new argument 'pt.cex'.
o plot.ts() has more arguments, particularly 'yax.flip'.
o heatmap() has a new 'keep.dendro' argument.
o The default barplot method now handles vectors and 1-d arrays
(e.g., obtained by table()) the same, and uses grey instead of
heat color palettes in these cases. (Also fixes PR#6776.)
o nls() now looks for variables and functions in its formula in
the environment of the formula before the search path, in the
same way lm() etc look for variables in their formulae.
DEPRECATED & DEFUNCT
o Support for non-IEEE-754 arithmetic (which has been untested
for some time) will be removed in the next full release.
o Direct use of R INSTALL|REMOVE|BATCH|COMPILE|SHLIB is
deprecated: use R CMD instead.
o The gnome/GNOME graphics device is deprecated and will be
removed in the next full release.
Plus Bug Fixes.
Changes since 11.1c:
Moved notification of polynomial factoring success to debug level 1 or higher.

I am thinking of making this a run-time option.
Increased security of "SECURE" compile-time define.
Absolutely no file operations are allowed or linked in.

Added "integrate" command.
Fixed "derivative" command.
Code cleanup.
Fixed "taylor" command.
The step from 1.0.12 to 1.2.12 is too large to mention all changes.
pkgsrc issues:
-use gnome2
-add python support (python23 provides a shared lib)
-XXX I've enabled libgda/gnomedb, this seems to be completelely
non-functional to me, but perhaps it is just my setup...
