cupyx.scipy.fftpack.ifft(x, n=None, axis=-1, overwrite_x=False)

Compute the one-dimensional inverse FFT.

  • 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 by axis is used.
  • axis (int) – Axis over which to compute the FFT.
  • overwrite_x (bool) – If True, the contents of x can be destroyed.

The transformed array which shape is specified by n and type will convert to complex if that of the input is another.

Return type:
