Hello to all,
I need and search a complete program wich calculate the complexx FFT of a matrix, so do anyone have an example?
thankx

Are you looking for a 2-D fft of a real matrix or of a complex matrix?

The specific functions and examples depend greatly on what version of Numerical Recipes and what language you are using.

Here are some possibilities with Numerical Recipes version 2 and version 3: Details are different for each and every case:

f77 (Version 2)

f90 (Version 2)

C (Version 2)

C++ (Version 2)

C++ (Version 3)
