Simple model that performs a matrix multiplication (C = A * B) where A and B are lower triangular matrices. A (torch.Tensor): Lower triangular matrix of shape (N, N). B (torch.Tensor): Lower ...

Abstract:Due to the robustness, the matrix inversion methods based on matrix factorization are often adopted in engineering while the triangular matrix inversion is one key part of those methods. This ...

Let be a polynomial matrix for where for, are square matrices of order n over the field F. If, then whenever (Zero matrix) implies Converse is not true. Proof. Since (3.1) is itself is a matrix of ...
