torch support with torch_complex #47

Closed boeddeker closed 2 years ago

boeddeker commented 4 years ago

Torch has only partial support for complex numbers (1.6.0.dev20200623). torch_complex implements complex operations as real operations. This PR adds support for torch_complex.

One drawback: It looks like the matrix inverse in torch_complex has some stability problems. Therefore, the implementation has an option to use torch.solve as alternative (Strangely torch.solve is implemented for complex numbers, while torch.matmul is not).

Deprecated. Torch has now native support and nara_wpe an implementation with native complex numbers.
