Abstract
Let be the combined matrix of an invertible matrix A, where
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."
