I'm looking for a freeware 3D FFT function that matches the
SGI math lib function cfft3d., but for alpha station.
I saw that SGI are relying on the netlib FFTPACK,
but no cfft3D is there.
The specifications I need are:
1. FFT that operates on a discrete 3D function with dimensions NxNxN.
2. As few limits on N as possible. 2 to the power of n is not acceptable.
3. Forward and backward transformations.
Thanks in advance
