cupyx.scipy.fft.ifftn(x, s=None, axes=None, norm=None, overwrite_x=False)

Compute the N-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 s is not given, the lengths of the input along the axes specified by axes are used.
  • axes (tuple of ints) – Axes over which to compute the FFT.
  • norm (None or 'ortho') – Normalization mode.
  • overwrite_x (bool) – If True, the contents of x can be destroyed.

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

Return type:
