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 1/n. It norm is set to “ortho”, the return values will be scaled by 1/\sqrt{n}.

Returns:

outndarray

The result of the inverse real 2-D FFT.

irfftn

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

Note

This is really irfftn() with different defaults. For more details see irfftn().
