cupy.fft.fft2

cupy.fft.fft2(a, s=None, axes=(- 2, - 1), norm=None)[source]

Compute the two-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 (None or "ortho") – Keyword to specify the normalization mode.

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
