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

saying "help".  You will get instructions on how to do ftp via email.


Everything in this index (except for what is on {net,stat}lib) is
mirrored in pub/sci/math/numcomp-free-c on nic.funet.fi
Note: this site is in finland.  If you are in the US, please try
to find a site closer to you.

source-code newsgroups:
        ftp.uu.net  (e.g. usenet/comp.sources.reviewed archives the
        comp.sources.reviewed newsgroup).
f2c:
        netlib/f2c on netlib.att.com
        pub/gnu on prep.ai.mit.edu
Netlib:
        netlib.att.com       email, ftp
        ornl.gov             email, xnetlib
        nac.no               email, xnetlib for Europe

        unix.hensa.ac.uk is a mail server useful for Europe.
        ci.cs.uow.edu.au (130.130.64.3) in Australia
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.  elib.ZIB-Berlin.de is quite interesting
        too.
