general prime factor algorithm (gpfa) FFT code in FORTRAN.


 ---- begin quote ----

Well, you might be interested in the Generalized Prime Factor FFT routines
based on Clive Temperton's GPFA algorithm.  I have tried out these routines
and they are the fastest I have benchmarked, in many cases faster than
supercomputer manufacturers assembly coded and tuned machine-dependant
ones.  (This is because of the superior algorithms used).

They are in FORTRAN, but there's always f2c.

Didn't see it, please don't ask questions about it !

Send me your C-translation of this code.
