- cupyx.scipy.fft.hfft(x, n=None, axis=-1, norm=None, overwrite_x=False, *, plan=None)[source]#
Compute the FFT of a signal that has Hermitian symmetry.
a (cupy.ndarray) – Array to be transform.
n (None or int) – Length of the transformed axis of the output. For
n//2+1input points are necessary. If
nis not given, it is determined from the length of the input along the axis specified by
axis (int) – Axis over which to compute the FFT.
"forward") – Optional keyword to specify the normalization mode. Default is
None, which is an alias of
overwrite_x (bool) – If True, the contents of
xcan be destroyed.
plan (None) – This argument is currently not supported.
The transformed array which shape is specified by
nand type will convert to complex if the input is other. If
nis not given, the length of the transformed axis is
2*(m-1)where m is the length of the transformed axis of the input.
