WebNov 17, 2024 · \$\begingroup\$ Based on the Sherman-Morrison formula, it seems that further mathematical simplifications can be done to throw away for-loops completely (and replace them with implicit vectorized PyTorch operations). BTW, your 'method 1' code does not incorporate all the improvements in the code of my previous review. E.g., copying the …
WebJan 14, 2024 · Finding the inverse of C is basically finding two real valued matrices x and y such that (A + jB)(x + jy) = I + j0 This boils down to solving the real valued system of equations: Now that we know how to do reduce a complex matrix inversion to real-valued matrix inversion, we can use pytorch's solve to do the inverse for us.
