cunumeric.fft.irfft2#

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

Computes the inverse of rfft2.

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 ({"backward", "ortho", "forward"}, optional) – Normalization mode (see numpy.fft). Default is “backward”. Indicates which direction of the forward/backward pair of transforms is scaled and with what normalization factor.

Returns

out – The result of the inverse real 2-D FFT.

Return type

ndarray

Notes

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