# 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.
