hfft(x, n=None, axis=-1, norm=None, overwrite_x=False)¶
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.
- norm (None or
"ortho") – Keyword to specify the normalization mode.
- overwrite_x (bool) – If True, the contents of
xcan be destroyed.
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.
