Welcome to of the index of free source code for numerical computation
written in either of C or C++.  I also give pointers to books which
come with source code (and hence act as low-cost libraries).

This file is numcomp-free-c.z in pub/C-numanal on usc.edu
(Note that this is the new gzip compression, you need gunzip to
uncompress it).
A slightly outdated version is c/numcomp-free-c on netlib.

Please see the section "interesting sites" below to get some help on
how to retrieve software listed here.

Table of Contents:

    * Explanations of fields
    * The index
    * f2c
    * Other pointers
    * Interesting sites
    * Books
    * Credits

The index is biased towards fields I work in.
Please send me suggestions, corrections and improvements.

Explanations of fields
----------------------

Name        if the archive has a obvious name, then that is shown.
            Otherwise I invent something sensible.
Where       is a pointer into a ftp site, or sufficient information to
            figure that out.  The information at EOF may enlighten
            you if you are still stuck.
Systems     The default is Unix.  If it runs on other systems this is shown,
            if it does NOT run on Unix this is shown.
Language    The default is ANSI C.  The alternatives are K&R and C++.
Author      I try to give the name(s) and email addresses.  Sometimes the
            email address is a contact person, even if it's not the author.
Version     This tries to identify a most-recent version and gives it's date.
Description A one-line description
Comments    Are a few keywords thrown in to help you egrep.

Many things are incomplete; tell me of anything which hurts your eyes.
Please point me to goodies I've overlooked.  If you have source code
which may be of wide interest, please make it available to the net.

Author      : Michel Berkelaar ([e-mail])
Comments    : Its core is a sparse matrix dual simplex LP solver.  MILP
              problems are solved with a branch-and-bound iteration over LP
              solutions. It uses a lex+yacc parser to read a human-friendly
              algebraic input format.  The author has used the program to
              solve LP problems up to about 30000 variables and 50000
              constraints (on a 22 MFLOPS HP9000/750).

Description : MADPACK is a a compact package for solving systems of
              linear equations using multigrid or aggregation
              disaggregation methods.  Imbedded in the algorithms
              are implementations for sparse Gaussian elimination
              and symmetric Gauss-Seidel (unaccelerated or
              accelerated by conjugate gradients or Orthomin(1)).
              This package is particularly useful for solving
              problems which arise from discretizing partial
              differential equations, regardless of whether finite
              differences, finite elements, or finite volumes are
              used.

Systems     : highly portable
Language    : C, Pascal, Ada
Authors     : G Marsaglia, M G Harmon & T P Baker, V Broman.
Description : highly machine-independent uniform RNG,
              requires 24-bit fixed point or floating point arithmetic.
              953118087 different seed pairs give pseudo-random sequences
              with period about 2**144.  passes stringent randomness tests.
Comments    : correct operation with 24-bit floats seems to require
              a guard bit.  failing that, try fixed point arithmetic.

Description : Several C-language codes for n * n matrix multiply, n a
              power of 2, developed as a laboratory exercise in the
              Spring of 1993 for MIT course 6.891, "Source Code
              Optimization for Workstations and Supercomputers."  The
              sources are commented, however the recursive SRM
              (shuffled-row major) algorithm is obscure.  Offered "as
              is" into the public domain by the course instructor.
