numpy.fft.fft2¶
- numpy.fft.fft2(a, s=None, axes=(-2, -1))¶
Compute the 2-D FFT of an array.
Parameters: a : array_like
Input array. The rank (dimensions) of a must be 2 or greater.
s : shape tuple
Shape of the FFT.
axes : sequence of 2 ints
The 2 axes over which to compute the FFT. The default is the last two axes (-2, -1).
Notes
This is really just fftn with different default behavior.
