cupyx.scipy.fftpack.ifft#
- cupyx.scipy.fftpack.ifft(x, n=None, axis=-1, overwrite_x=False, plan=None)[source]#
Compute the one-dimensional inverse FFT.
- Parameters
x (cupy.ndarray) – Array to be transformed.
n (None or int) – Length of the transformed axis of the output. If
n
is not given, the length of the input along the axis specified byaxis
is used.axis (int) – Axis over which to compute the FFT.
overwrite_x (bool) – If True, the contents of
x
can be destroyed.plan (
cupy.cuda.cufft.Plan1d
orNone
) –a cuFFT plan for transforming
x
overaxis
, which can be obtained using:plan = cupyx.scipy.fftpack.get_fft_plan(x, axis)
Note that plan is defaulted to None, meaning CuPy will use an auto-generated plan behind the scene.
- Returns
The transformed array which shape is specified by
n
and type will convert to complex if that of the input is another.- Return type
Note
The argument plan is currently experimental and the interface may be changed in the future version.
