cupyx.scipy.fftpack.fft¶
-
cupyx.scipy.fftpack.
fft
(x, n=None, axis=-1, overwrite_x=False, plan=None)¶ Compute the one-dimensional 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) –
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.
