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.Reconocimiento (by)H-matrixCombined matrixIrreducibilityDiagonally equipotent matrixMATEMATICA APLICADAArtículo10.1515/spma-2023-0101Abierto
