symjax.tensor.fft.rfft2

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

Compute the 2-dimensional FFT of a real array.

LAX-backend implementation of rfft2(). Original docstring below.

Parameters:
  • a (array) – Input array, 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) –

    New in version 1.10.0.
Returns:

out – The result of the real 2-D FFT.
Return type:

ndarray

Notes

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