Welcome to $Revision: 1.1 $ of the index of free source code for
numerical computation written in either of C or C++.  The most
recent version of this file may be found in netlib/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
