cupy.fft.
ifft2
(a, s=None, axes=(-2, -1), norm=None)[source]¶ Compute the two-dimensional inverse FFT.
Parameters: - a (cupy.ndarray) – Array to be transform.
- s (None or tuple of ints) – Shape of the transformed axes of the
output. If
s
is not given, the lengths of the input along the axes specified byaxes
are used. - axes (tuple of ints) – Axes 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
s
and type will convert to complex if the input is other.Return type: See also
