numpy.fft.irfft2()

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

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

Parameters:

Parameters:	a : array_like The input array s : sequence of ints, optional Shape of 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.

a : array_like

The input array

s : sequence of ints, optional

Shape of 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.

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