ifft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False)¶
Compute the two-dimensional inverse FFT.
- x (cupy.ndarray) – Array to be transformed.
- s (None or tuple of ints) – Shape of the transformed axes of the
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') – Normalization mode.
- overwrite_x (bool) – If True, the contents of
xcan be destroyed.
The transformed array which shape is specified by
sand type will convert to complex if that of the input is another.
