cupyx.scipy.fft.hfft¶

cupyx.scipy.fft.hfft(x, n=None, axis=-1, norm=None, overwrite_x=False)¶

Compute the FFT of a signal that has Hermitian symmetry.

Parameters:	a (cupy.ndarray) – Array to be transform. n (None or int) – Length of the transformed axis of the output. For `n` output points, `n//2+1` input points are necessary. If `n` is not given, it is determined from the length of the input along the axis specified by `axis`. axis (int) – Axis over which to compute the FFT. norm (None or `"ortho"`) – Keyword to specify the normalization mode. overwrite_x (bool) – If True, the contents of `x` can be destroyed.
Returns:	The transformed array which shape is specified by `n` and type will convert to complex if the input is other. If `n` is not given, the length of the transformed axis is `2*(m-1)` where m is the length of the transformed axis of the input.
Return type:	cupy.ndarray
