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

aarray_like

The input array

ssequence of ints, optional

Shape of the real output to the inverse FFT.

axessequence 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

outndarray

The result of the inverse real 2-D FFT.
