cunumeric.fft.rfft2#

cunumeric.fft.rfft2(a, s=None, axes=(- 2, - 1), norm=None)#

Compute the 2-dimensional FFT of a real array.

Parameters

a (array) – Input array, taken to be real.
s (sequence of ints, optional) – Shape of the FFT.
axes (sequence of ints, optional) – Axes over which to compute the FFT.
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 real 2-D FFT.

Return type

ndarray

Notes

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