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

aarray

Input array, taken to be real.

ssequence of ints, optional

Shape of the FFT.

axessequence 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

outndarray

The result of the real 2-D FFT.
