FFT

 
FFT of complex data sequence (forward or inverse) - any number of points. Useful
for multivariate transforms. Uses only real arithmetic.
 
Classes  :  J1a2 . One-dimensional complex fast Fourier transforms
            J1b .  Multidimensional fast Fourier transforms
 
Type     : Fortran subroutine in PORT library (FFT sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Single.
 
Usage    : CALL FFT (A,B,NTOT,N,NSPAN,ISN)
 
Details  : Source
Sites    : (1) NETLIB
