mars.tensor.fft.
rfft2
Compute the 2-dimensional FFT of a real tensor.
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.
out – The result of the real 2-D FFT.

Notes
This is really just rfftn with different default behavior. For more details see rfftn.
