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.
