David,

As for replacing the Fourier Transform calls from the libsci, you can use a
library which I have written when I was at Idris and which is a plug-in
replacement for these calls.

You can find it at the following URLs
"http://www.idris.fr/data/publications/JMFFT/jmfft-7.2.tar.gz" (a Fortran 90
version) and "http://www.idris.fr/data/publications/JMFFT/jmfftc-1.0.tar.gz" (a
C version).

If you choose to build the C library, and if you call it from a Fortran program,
you will most probably run into the usual interface problems between Fortran and
C. They can be solved very simply by changing the "#define" statements in the
file "jmfftf2c.c".

There is a Web page at "http://www.idris.fr/data/publications/JMFFT/".
Unfortunately, it is in French!

Truly,

Jean-Marie Teuler
