numpy.fft.irfft2

numpy.fft.irfft2(a, s=None, axes=(-2, -1), norm=None)

Compute the 2-dimensional inverse FFT of a real array.

Parameters:

a : array_like

The input array

s : sequence of ints, optional

Shape of the real output to the inverse FFT.

axes : sequence of ints, optional

The axes over which to compute the inverse fft. Default is the last two axes.

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 inverse real 2-D FFT.
