- cupyx.scipy.fftpack.ifft(x, n=None, axis=- 1, overwrite_x=False, plan=None)¶
Compute the one-dimensional inverse FFT.
x (cupy.ndarray) – Array to be transformed.
axis (int) – Axis over which to compute the FFT.
overwrite_x (bool) – If True, the contents of
xcan be destroyed.
a cuFFT plan for transforming
axis, 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.
The transformed array which shape is specified by
nand type will convert to complex if that of the input is another.
- Return type
The argument plan is currently experimental and the interface may be changed in the future version.
