(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False)¶ Compute the two-dimensional inverse FFT for real input.
Parameters: - a (cupy.ndarray) – Array to be transform.
- s (None or tuple of ints) – Shape of the output. If
s
is not given, they are determined from the lengths of the input along the axes specified byaxes
. - axes (tuple of ints) – Axes over which to compute the FFT.
- norm (None or
"ortho"
) – Keyword to specify the normalization mode. - overwrite_x (bool) – If True, the contents of
x
can be destroyed.
Returns: The transformed array which shape is specified by
s
and type will convert to complex if the input is other. Ifs
is not given, the length of final transformed axis of output will be 2*(m-1) where m is the length of the final transformed axis of the input.Return type: Warning
The input array may be modified in CUDA 10.1 and above, even when overwrite_x is False.
