- cupyx.scipy.fft.ifft2(x, s=None, axes=(- 2, - 1), norm=None, overwrite_x=False, *, plan=None)#
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 output. 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.
"forward") – Optional keyword to specify the normalization mode. Default is
None, which is an alias of
overwrite_x (bool) – If True, the contents of
xcan be destroyed.
a cuFFT plan for transforming
axes, which can be obtained using:
plan = cupyx.scipy.fftpack.get_fft_plan(x, s, axes)
planis defaulted to
None, meaning CuPy will use an auto-generated plan behind the scene.
The transformed array which shape is specified by
sand type will convert to complex if that of the input is another.
