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.
