Hi Peter, Well, seems like I just overlooked that feature. I didn't check your 'claims' yet, but it sounds like my problem is solved. Thanks a lot. Cheers, Christian On Nov 23, 2004, at 12:16 PM, Peter Verveer wrote:
Numarray has N-dimensional fft's, they are just not documented in the manual (this should be fixed, will do that as soon as find the time). There are the following functions in numarray.fft:
fftnd() inverse_fftnd() real_fftnd() inverse_real_fftnd()
They are documented in the source code, try the following:
from numarray import fft help(fft.fftnd)
Or alternatively, implement your 3D fft as a sequence of three 1D fft's.
Cheers, Peter

Hi
I only hope that you guys on this list can help me, for I didn't find a list specified on numarray.
Well, may problem is that I want to write an algorithm where I combine amplitude data from one 3D-image volume with phase data from another. (Actually they are identical except for one small correction, that's why this should be legal.) Numarray only offers 1D and 2D FFTs. I could possibly implement a 3D transform, but if somebody already has written something like this, it would be very nice if one could point me on an URL for this.
Thanks a lot in advance.
Cheers Christian Meesters
