Huh? From the FFT module which comes with Numeric:

In [1]: import FFT

In [2]: FFT.fft2d?
Type:           function
Base Class:     <type 'function'>
String Form:    <function fft2d at 0x1444fb0>
Namespace:      Interactive
File:           /platlib/Numeric/FFT/FFT.py
Definition:     FFT.fft2d(a, s=None, axes=(-2, -1))
Docstring:
     fft2d(a, s=None, axes=(-2,-1))

     The 2d fft of a. This is really just fftnd with different default
     behavior.
