LINPACK is a collection of Fortran subroutines that analyze and solve
linear equations and linear least-squares probles. The package solves
linear systems whose matrices are general, banded, symmetric
indefinite, symmetric positive definite, triangular, and tridiagonal
square. In addition, the package computes the QR and singular value
decompositions of rectangular matrices and applies them to
least-squares problems. LINPACK uses column-oriented algorithms to
increase efficiency by preserving locality of reference.
LINPACK was designed for supercomputers in use in the 1970s and early
1980s. LINPACK has been largely superceded by LAPACK which has been
designed to run efficiently on shared-memory, vector supercomputers.
BUG FIXES
- t-functions using ellipsis argument (...) crashed Tela (this was due to the
"deep" copy object array feature introduced in previous version 1.31, cure
was to introduce another internal type KShallowObjectArray which is now used
in Tprg::execute() in prg.C)
- memory leak in object arrays (object.C:Tobject::setsize, deep clear was missing)
(also this bug existed only in version 1.31, not before, because object array
semantics was changed from shallow copy to deep copy in 1.31).
USER-VISIBLE CHANGES
- new diag() function contributed by Ch.Spiel which allows a second input argument
specifying the super- or sub-diagonal (the default zero meaning the main diagonal),
this function is compatible with Matlab's and also compatible with the old diag()
function (std.ct)
- added global symbol NaN if compiler supports NaN's (ieee754.h header is present and working) (tela.C)
and cause problems if left.
Touch "parse.cc" and "parse.h" so that they won't get remade. (The configure
script doesn't detect bison correctly anyway).
Remove a duplicate entry from PLIST.
Make it work with the readline currently in pkgsrc.

This library contains routines to compute cumulative distribution
functions, inverses, and parameters of the distribution for the
following set of statistical distributions:
(1) Beta
(2) Binomial
(3) Chi-square
(4) Noncentral Chi-square
(5) F
(6) Noncentral F
(7) Gamma
(8) Negative Binomial
(9) Normal
(10) Poisson
(11) Student's t
(12) Noncentral t
Given values of all but one parameter of a distribution, the other is
computed. These calculations are done with FORTRAN Double Precision
variables.
Thanks to the scilab folks at INRIA for helping us get rid of 9 more patches!

INCOMPATIBLITY
==============
help and scicos palettes handling have changed.
Fraclab toolbox has been moved to the contributions part and is no
more included in the package
The Communication Toolbox (geci) is now obsolete. It will be removed in
next release. Use PVM instead.
2.1.5 --> 2.2
-------------
Bug fixes:
- The sign convention for rotation angles was not correctly applied
in Scientific.Geometry.Transformation and Scientific.Geometry.Quaternions.
Everything was consistent, but with the wrong sign.
Improvements:
- Scientific.IO.PDB can handle a larger range of variant formats for DNA
New features:
- New module Scientific.Visualization.VPython.
- Scientific.IO.TextFile also handles bzip2 compressed files
(extension .bz2). This only works if bzip2 is installed.
2.1.4 --> 2.1.5
---------------
New features:
- Scientific.TkWidgets.TkPlotCanvas:
- Popup menu on right button
- Value display on middle button
- HorizontalLine, VerticalLine objects
Modifications:
- MPI interface no longer assumes that MPI_Op and MPI_Datatype are
integers (they aren't in LAM, for example).
2.1.3 --> 2.1.4
---------------
New features:
- New MPI functions implemented by Jakob Schiotz:
- nonblocking send and receive
- abort
- reduce and allreduce
Modifications:
- The Python interpreter lock is released during calls to the netCDF
library, permitting other threads to continue during I/O operations.
An internal lock has been added to prevent reentrant calls to the
netCDF library, which is not thread safe.
(If you don't understand any of this, you shouldn't care, it has
no consequences unless you use threads.)
- Methods receive and receiveString on MPI communicator objects
can be called without source and tag arguments (defaults to None).
Bug fixes:
- The compilation script did not work correctly for MPI support
2.1.2 --> 2.1.3
---------------
New features:
- Some small utility widgets have been added to Scientific.TkWidgets.
They are not particularly "scientific", but not worth the effort
of a separate distribution.
Bug fixes:
- The abs() function didn't work on DerivVar objects (modules
Scientific.Functions.Derivatives and Scientific.Functions.FirstDerivatives)
with negative values.
- The method projectionOf in Scientific.Geometry.Objects3D.Plane was
wrong.
2.1.1 --> 2.1.2
---------------
Installation:
- The mpipython executable is compiled using 'mpicc', which should simplify
installation significantly because all library specifications are
automatically taken into account. In other words, MPI support should
work on all platforms without any modifications to the Setup file.
(Thanks to Jakob Schiotz for this suggestion!)
- Some 'extern' declarations were changed to 'staticforward' to please
some compilers.
Documentation:
- the documentation for the methods receive and receiveString were
wrong.
2.1.0 --> 2.1.1
---------------
Bug fixes:
- The upper bound for MPI message tags was not treated correctly,
leading to a bound of zero on some platforms.
Modifications:
- The methods sendArray and sendString were combined into a single
method send.
- broadcastArray was renamed to broadcast, shareArray was renamed to share,
receiveArray was renamed to receive. The only function that retains
a data type indication is receiveString.
2.0.1 --> 2.1.0
---------------
Additions:
- MPI interface in Scientific.MPI
* What is new in gsl-0.7:
** Linux/PowerPC should now be well supported.
** Header files for common physical constants have been added.
** Functions linear and nonlinear regression in one or more dimensions
are now available.
** Vector and matrix views now have access to the address of the
underlying block for compatibility with VSIPL (www.vsipl.org).
** There is a new library for generating low-discrepancy quasi-random
sequences.
** The seeding procedure of the default random number generator
MT19937 has been updated to match the 10/99 release of the original
code. This fixes a weakness which occurred for seeds which were
powers of 2.
** The blas library libgslblasnative has been renamed libgslblas to avoid
confusion with system blas library
o add @exec/@unexecinstall-info directives to PLIST
o slightly change the path's for the documentation
(share/doc/octave instead of share/octave/doc etc.)
o install html docs into share/doc/html/octave
first component is now a package name+version/pattern, no more
executable/patchname/whatnot.
While there, introduce BUILD_USES_MSGFMT as shorthand to pull in
devel/gettext unless /usr/bin/msgfmt exists (i.e. on post-1.5 -current).
Patch by Alistair Crooks <agc@netbsd.org>
to be bug fixes mostly, plus a couple of new features:
* Release 'Mini-Morten' -- a cute little thing of
about 3k She leaks, though. (Congratulations !)
* Reworking plugin architecture to support JIT loading
* Improve scrollbar and enable optional live scrolling
* Add a sample implementation of python based scripting
The API is written in sand so don't get comfortable
* Enable indent from left and right
* Persist sheet prefs
Version 1.31 (Released 8 Mar 2001)
----------------------------------
USER-VISIBLE CHANGES
- copying an object array (see help voids) is now "deep" copy rather than "shallow" copy.
This means that when an object array is assigned to another variable, a completely new
copy is made (before, only the first array level was copied). Mostly this won't affect
you at all because (1) you are using object arrays only if you are using voids() in some
phase in your program, (2) if you are, then you are probably using only single-level
object array. The old behaviour was simply stupid. Object arrays are a crude but working
mechanism for using heterogeneous combined types in Tela; the only relevant function
(in the present Tela version) is voids(), which acts as a constructor for such things.
Thanks to Ch. Spiel for suggesting this change (object.C).
- quit() and exit() now accept input argument (the exit value) (std.ct)
- sort() function now accepts second input argument (user-defined comparison function) (std.ct)
(old function still available as sort_old in case of problems).
- slight change in semantics of --shared option for telakka (telakka.in)
The above were contributed by Christoph Spiel <cspiel@hammersmith-consulting.com>
- added incomplete gamma and beta functions (specfun.t)
(specfun.t not autoloaded, but after source("specfun.t") functions are available).
- added function polymul and added polyadd,polymul to autoload (poly.t,telainit.t)
- added function applyfilter (numerics.ct)
- added functionwise profiling option (tela -p) (tela.C,prg.C)
BUG FIXES
- doing dot product (**) of two zero-length integer vectors produced a LAPACK error message
and Tela quit (la.ct)
- tree.C:DeleteObjects() accessed memory after it being freed, which however did not cause
any problems in practice (unless using malloc debug libraries), but is anyway now fixed
INTERNAL CHANGES
- Some modernizations in configure script (e.g., now tries to link with
libatlas by default instead of libblas if available) (configure.in)
PARI-GP is a package which is aimed at efficient computations in
number theory, but also contains a large number of other useful
functions. It is somewhat related to a Computer Algebra System, but
is not really one since it treats symbolic expressions as mathematical
entities such as matrices, polynomials, series, etc..., and not as
expressions per se. However it is often much faster than other CAS,
and contains a large number of specific functions not found elsewhere,
essentially for use in number theory.
This package can be used in an interactive shell (GP) or as a C/C++
library (PARI). It is free software, in the sense of freedom AND 'free
of charge'.
For a changelog, I didn't find more than:
Numeric 17.3.0 is intended to be the last release before adding
capabilities supported by Python 2.1. This is a routine catch-up to CVS
release.
using the newest PNG library won't work on system with an older one. To
prevent such problems with precompiled binary packages require at least
"png-1.0.9nb1" in all dependences.
Tela (TEnsor LAnguage) is a scientific computing language and
environment. It is mainly targeted for prototyping large-scale
numerical simulations and doing pre- and postprocessing for them, and
it replaces a compiled language like C++ or Fortran in this
respect. The feature set is therefore biased to operations needed in
partial differential equation solvers. A relatively complete graphics
is included via a separate program (PlotMTV). Tela uses HDF format as
native save/load format. It can also read/write Matlab binary files
and some ASCII files.
Tela is generally 2-4 times faster than Matlab, the extremeties
encountered so far are 0.9-11. Even though Tela is mainly a
prototyping and development environment, modest-size 2D simulations
can be run in modern (1994) desktop workstations while preserving
"interactive" response times. Only large 2D or 3D simulations must
usually be coded in C or Fortran and run on supercomputers.
METIS is a family of programs for partitioning unstructured graphs and
hypergraphs and computing fill-reducing orderings of sparse matrices.
The underlying algorithms used by METIS are based on the
state-of-the-art multilevel paradigm that has been shown to produce
high quality results and scale to very large problems. It is
available both as a set of stand-alone programs and as a library.
Strictly numerical libraries, like fftpack, work fine, but some
which make use of Fortran I/O have problems resolving symbols.
This is a known problem with g77/f2c.
Convert most MESSAGE files to new syntax (${VARIABLE} gets replaced,
not @VARIABLE@, nor @@VARIABLE@@).
By default, substitutions are done for LOCALBASE, PKGNAME, PREFIX,
X11BASE, X11PREFIX; additional patterns can be added via MESSAGE_SUBST.
Clean up some packages while I'm there; add RCS tags to most MESSAGEs.
Remove some uninteresting MESSAGEs.
Changes from former versions of ARIBAS to the present version:
V1.14 (April 1999) to V1.20 (Jan. 2001)
- floating point precision can be set up to 4096 bits (over
1200 decimal places); former limit was 192 bits
- bugfix in function mem_byteswap()
- make_unbound(user) unbinds all user defined functions
- new function max_intsize(); returns maximal number
of decimal places of an integer
