mars.tensor.fft.rfft2#

mars.tensor.fft.rfft2(a, s=None, axes=(-2, -1), norm=None)[source]#

Compute the 2-dimensional FFT of a real tensor.

Parameters

  • a (array_like) – Input tensor, taken to be real.

  • s (sequence of ints, optional) – Shape of the FFT.

  • axes (sequence of ints, optional) – Axes over which to compute the FFT.

  • norm ({None, "ortho"}, optional) – Normalization mode (see mt.fft). Default is None.

Returns

out – The result of the real 2-D FFT.

Return type

Tensor
