cupyx.scipy.fft.hfftn(x, s=None, axes=None, norm=None, overwrite_x=False, *, plan=None)[source]#

Compute the FFT of a N-dimensional signal that has Hermitian symmetry.

  • x (cupy.ndarray) – Array to be transformed.

  • s (None or tuple of ints) – Shape of the real output.

  • axes (tuple of ints) – Axes over which to compute the FFT.

  • norm ("backward", "ortho", or "forward") – Optional keyword to specify the normalization mode. Default is None, which is an alias of "backward".

  • overwrite_x (bool) – If True, the contents of x can be destroyed. (This argument is currently not supported)

  • plan (None) – This argument is currently not supported.


The real result of the N-D Hermitian complex real FFT.
