irfft
(a, n=None, axis=-1, norm=None)[source]¶ Compute the one-dimensional inverse FFT for real input.
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. Ifn
is not given, it is determined from the length of the input along the axis specified byaxis
. - axis (int) – Axis over which to compute the FFT.
- norm (None or
"ortho"
) – Keyword to specify the normalization mode.
Returns: The transformed array which shape is specified by
n
and type will convert to complex if the input is other. Ifn
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: See also
