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.

rfftn

Compute the N-dimensional discrete Fourier Transform for real input.

Notes

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