- cupy.fft.rfft(a, n=None, axis=-1, norm=None)#
Compute the one-dimensional FFT for real input.
a (cupy.ndarray) – Array to be transform.
n (None or int) – Number of points along transformation axis in the input to use. If
nis not given, 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
The transformed array which shape is specified by
nand type will convert to complex if the input is other. The length of the transformed axis is
