Greetings,
Joerg Stiller's request was for a free f90-compatible FFT routine, but I
can't help mentioning the
"Numerical Recipes in Fortran 90" collection. It's so cheap it's
negligible. The thread has been
emphasizing the trueness of the f90 also, and I'm not sure what that means.
If it means finely
crafted and using F90's powers intelligently I think NR fills the bill.
Another approach, if you have some C examples, is to use Dave Gemini's
C2F translator, as
posted on the Unicomp site. It has worked for me sometimes; when it hasn't
I suspect that
I hadn't gathered all the pesky header files that language abounds in.
While the topic is alive, has anyone seen the venerable Mcclellan-Parks FIR
routine done in
clean F90? It's not essential, as it performs fine, but the spaghettiness
of the usual f77
examples disturbs my refined sense of rightness.
