nlcpy.fft.irfft2

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

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

Parameters

aarrayi_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

Normalization mode. By default(None), the transforms are scaled by . It norm is set to “ortho”, the return values will be scaled by .

Returns

outndarray

The result of the inverse real 2-D FFT.
