numpy.fft.rfftn¶
- numpy.fft.rfftn(a, s=None, axes=None)¶
Compute the n-dimensional fft of a real array.
Parameters: a : array (real)
input array
s : sequence (int)
shape of the fft
axis : int
axis over which to compute the fft
Notes
A real transform as rfft is performed along the axis specified by the last element of axes, then complex transforms as fft are performed along the other axes.
