FreeMat is a free environment for rapid engineering and scientific
prototyping and data processing. It is similar to commercial systems
such as MATLAB from Mathworks, and IDL from Research Systems, but is
Open Source. FreeMat includes several novel features such as a codeless
interface to external C/C++/FORTRAN code, parallel/distributed
algorithm development (via MPI), and plotting and visualization
capabilities.
UMFPACK is a set of routines for solving unsymmetric sparse linear
systems, Ax=b, using the Unsymmetric MultiFrontal method. Written
in ANSI/ISO C, with a MATLAB (Version 6.0 and later) interface.
Appears as a built-in routine (for lu, backslash, and forward
slash) in MATLAB. Includes a MATLAB interface, a C-callable
interface, and a Fortran-callable interface.
AMD is a set of routines for ordering a sparse matrix prior to Cholesky
factorization (or for LU factorization with diagonal pivoting). There
are versions in both C and Fortran. A MATLAB interface is provided.
Note that this software has nothing to do with AMD the company.
Integer factorization library and program using the Elliptic
Curve Method (ECM), the P-1 or P+1 methods (which the ECM
method can be viewed as a generalization of).

PLplot is a library of functions that are useful for making scientific
plots. PLplot can be used from within compiled languages such as C, C++,
Fortran and Java, and interactively from interpreted languages such as
Octave, Python, Perl and Tcl.
The PLplot library can be used to create standard x-y plots, semilog
plots, log-log plots, contour plots, 3D surface plots, mesh plots,
bar charts and pie charts. Multiple graphs (of the same or different
sizes) may be placed on a single page with multiple lines in each
graph.
some initial work by Matthias Kilian.
thanks to the people who tested this.
LAPACK is written in Fortran77 and provides routines for solving systems
of simultaneous linear equations, least-squares solutions of linear
systems of equations, eigenvalue problems, and singular value problems.
The BLAS (Basic Linear Algebra Subprograms) are routines that provide
standard building blocks for performing basic vector and matrix
operations.

other port changes:
- use math/fftw3 library
- fix MASTER_SITES
- add a few patches to include correct headers
- build all HTML documentation and adjust BUILD_DEPENDS accordingly

FFTW is a C subroutine library for computing the discrete Fourier
transform (DFT) in one or more dimensions, of arbitrary input size,
and of both real and complex data (as well as of even/odd data, i.e.
the discrete cosine/sine transforms or DCT/DST).
From Steven Mestdagh <steven.mestdagh@esat.kuleuven.be>
Major changes includes speed improvements when reading large matrices
from file and the addition of the clmorder tool.

Mathomatic is a small, portable, general purpose CAS (Computer
Algebra System) written entirely in C. This is a console mode
application that compiles and runs under any operating system with
a C compiler.
aamath is a program that reads mathematical expressions in infix
notation and renders them as ASCII art. It may be useful to send
mathematics through text-only media, such as e-mail or newsgroups.
From Matthias Kilian <kili@outback.escape.de>
- Fix MODULE as only converters/libiconv is needed
- Put LOCALBASE/lib before X11BASE/lib so correct version of libexpat will
be used
- Bump PKGNAME

This package is a Perl interface to famous library PARI for
numerical/scientific/number-theoretic calculations. It allows use of
most PARI functions as Perl functions, and (almost) seamless merging of
PARI and Perl data. In what follows we suppose prior knowledge of what
PARI is (see <ftp://megrez.math.u-bordeaux.fr/pub/pari>, or
Math::libPARI).
ok sturm@
The PARI system is a package which is capable of doing formal
computations on recursive types at high speed; it is primarily
aimed at number theorists, but can be used by anybody whose primary
need is speed.
It is possible to use PARI in two different ways:
1) as a library, which can be called from an upper-level language
application (for instance written in C, C++, Pascal or Fortran);
2) as a sophisticated programmable calculator, named gp, which
contains most of the control instructions of a standard language
like C.
