nlcpy.fft.rfft2

nlcpy.fft.rfft2(a, s=None, axes=(- 2, - 1), norm=None)[ソース]

Computes the 2-dimensional FFT of a real array.

Parameters

aarray: Input array, taken to be real.
ssequence of ints, optional: Shape of the FFT.
axessequence of ints, optional: Axes over which to compute the FFT.
norm{None, "ortho"},optional: Normalization mode. By default(None), the transforms are unscaled. It norm is set to "ortho", the return values will be scaled by $1/\sqrt{n}$ .

Returns

参考

rfftn: Computes the n-dimensional discrete fourier transform for a real array.

注釈

This is really just rfftn() with different default behavior. For more details see rfftn().
