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 ...

In this paper, a study is made on two well-known operator matrices; the Rhaly operator Rₐ and the generalized difference operator Δab. Firstly, some compactness results for the operators Rₐ and Δab, ...

Abstract: Superregular matrices have the property that all of their submatrices, which can be full rank are so. Lower triangular superregular matrices are useful for e.g., maximum distance separable ...

If the entries on the main diagonal of a upper or lower triangular matrix are all 1, the matrix is called upper or lower unitriangular. Strictly triangular matrix: If all of the entries on the main ...

In the paper, the authors establish two identities to express higher order derivatives and integer powers of the generating function of the Chebyshev polynomials of the second kind in terms of integer ...

The constrained least-squares n × n-matrix problem where the feasibility set is the subspace of the Toeplitz matrices is analyzed. The general, the upper and lower triangular cases are solved by ...

Abstract: LDPC codes have become the most popular error control code in various fields like telecommunication, magnetic recording etc. due to their high error ...
