numpy.fft.rfft2()

numpy.fft.rfft2(a, s=None, axes=(-2, -1), norm=None) [source]

Compute the 2-dimensional FFT of a real array.

Parameters:

a : array

Input array, taken to be real.

s : sequence of ints, optional

Shape of the FFT.

axes : sequence of ints, optional

Axes over which to compute the FFT.

norm : {None, ?ortho?}, optional

New in version 1.10.0.

Normalization mode (see numpy.fft). Default is None.

Returns:

out : ndarray

The result of the real 2-D FFT.

Notes

This is really just rfftn with different default behavior. For more details see rfftn.
