rfft
(x, n=None, axis=-1, overwrite_x=False)¶ Compute the one-dimensional FFT for real input.
The returned real array contains
[y(0),Re(y(1)),Im(y(1)),...,Re(y(n/2))] # if n is even [y(0),Re(y(1)),Im(y(1)),...,Re(y(n/2)),Im(y(n/2))] # if n is odd
Parameters: - x (cupy.ndarray) – Array to be transformed.
- n (None or int) – Length of the transformed axis of the output. If
n
is not given, the length of the input along the axis specified byaxis
is used. - axis (int) – Axis over which to compute the FFT.
- overwrite_x (bool) – If True, the contents of
x
can be destroyed.
Returns: The transformed array.
