Combined matrix of diagonally equipotent matrices
[EN] LetC(A) = A (sic) A(-T) be the combined matrix of an invertible matrix A, where (sic) means the Hadamard product of matrices. In this work, we study the combined matrix of a nonsingular matrix, which is an H-matrix whose comparison matrix is singular. In particular, we focus on C(A) when A is d...

| Sumario: | [EN] LetC(A) = A (sic) A(-T) be the combined matrix of an invertible matrix A, where (sic) means the Hadamard product of matrices. In this work, we study the combined matrix of a nonsingular matrix, which is an H-matrix whose comparison matrix is singular. In particular, we focus on C(A) when A is diagonally equipotent, and we study whether C(A) is an H-matrix and to which class it belongs. Moreover, we give some properties on the diagonal dominance of these matrices and on their comparison matrices. |
