numpy.fft.rfft2

numpy.fft.rfft2(a, s=None, axes=(-2, -1))

Compute the 2-dimensional fft of a real array.

Parameters:

a : array (real)

input array

s : sequence (int)

shape of the fft

axis : int

axis over which to compute the fft

Notes

The 2-D fft of the real valued array a. This is really just rfftn with different default behavior.
