mars.tensor.fft.irfft2#

mars.tensor.fft.irfft2(a, s=None, axes=(-2, -1), norm=None)[source]#

Compute the 2-dimensional inverse FFT of a real array.

Parameters

  • a (array_like) – The input tensor

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

  • axes (sequence of ints, optional) – The axes over which to compute the inverse fft. Default is the last two axes.

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

Returns

out – The result of the inverse real 2-D FFT.

Return type

Tensor
