numpy.fft.irfftn¶
- numpy.fft.irfftn(a, s=None, axes=None)¶
Compute the n-dimensional inverse fft of a real array.
Parameters: a : array (real)
input array
s : sequence (int)
shape of the inverse fft
axis : int
axis over which to compute the inverse fft
Notes
The transform implemented in ifftn is applied along all axes but the last, then the transform implemented in irfft is performed along the last axis. As with irfft, the length of the result along that axis must be specified if it is to be odd.
