Welcome to $Revision: 1.4 $ of the index of free source code for
numerical computation written in either of C or C++.
This file is also stored on netlib, it's c/free-c.

Table of Contents:

* Explanations of fields
* The index
* f2c
* Other pointers
* Interesting sites
* 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     If it does not run on "almost any computer on earth", a
            list of systems is shown.
Language    If it's not ANSI C, then the language is shown.  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; please 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.

* f2c

In case you had not already noticed it: a public domain, industrial
strength, fortran-to-C translator named f2c exists.  It has one great
strength and one great weakness: "It is a true compiler".  Thus the
code generated always "works", at the price of frequently looking like
fortran.

A lot of useful fortran libraries can readily be turned into working C
using f2c, and the resulting C can often be made almost human after
some hand-editing.  The weakest link of f2c is code which involves
matrices.

A pointer to f2c is at EOF.  f2c is also inside Netlib, so you are
probably better off figuring out how to use Netlib.


* Other pointers:

There is a lot of interesting C source in these fields which I know nothing
about:
        - signal processing
        - pattern recognition, neural networks
The comp.dsp FAQ has some pointers to source code.
Please send me complete entries to include in the above index.

A lot of 3rd party source code which hooks into the S statistical package
uses computational engines written in C.  With a little work you can extract
useful source from this.  Look in the S directory on Statlib for more
pointers.  If you find something which is remarkably useful and easy
to extract, please tell me about it.

The same phenomenon operates to some extent for the XLispStat package.
Look around on the umnstat.stat.umn.edu site.


* Interesting sites:

If you don't have ftp access, send email to ftpmail@decwrl.dec.com
saying "help".  You will get instructions on how to do ftp via email.

source-code newsgroups:

        prep.ai.mit.edu
Netlib:
        netlib@ornl.gov is a mail server useful for the US
        research.att.com
        ci.cs.uow.edu.au (130.130.64.3)
        lanl.gov (ornl.gov?) in pub/clamsx/MATH.SOFTWARE
        netlib@unix.hensa.ac.uk is a mail server useful for UK/Europe.
Statlib:
        lib.stat.cmu.edu (as statlib)
        dmssyd.syd.dms.csiro.au (130.155.96.1)
others:
        qiclab.scn.rain.com has a small collection in pub/math, including
            fft stuff not listed above
