rfftn(a, s=None, axes=None, norm=None)¶
Compute the N-dimensional FFT for real input.
- a (cupy.ndarray) – Array to be transform.
- s (None or tuple of ints) – Shape to use from the input. If
sis not given, the lengths of the input along the axes specified by
- axes (tuple of ints) – Axes over which to compute the FFT.
- norm (None or
"ortho") – Keyword to specify the normalization mode.
The transformed array which shape is specified by
sand type will convert to complex if the input is other. The length of the last axis transformed will be
