cupy.fft.fftn#

cupy.fft.fftn(a, s=None, axes=None, norm=None)[source]#

Compute the N-dimensional FFT.

Parameters:

  • a (cupy.ndarray) – Array to be transform.

  • 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 ("backward", "ortho", or "forward") – Optional keyword to specify the normalization mode. Default is None, which is an alias of "backward".

Returns:

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

Return type:

cupy.ndarray
