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:
They are documented in the source code, try the following:
>>> from numarray import fft
Or alternatively, implement your 3D fft as a sequence of three 1D fft's.
