چکیده
|
We study the combined matrix of a nonsingular h-matrix. these matrices can belong to two different h-matrices classes: the most common,invertible class,and one particular class named mixed class. different results regarding diagonal dominance of the inverse matrix and the combined matrix of a nonsingular h-matrix belonging to the referred classes are obtained. we conclude that the combined matrix of a nonsingular h-matrix is always diagonally dominant and then it is an h-matrix. in particular,the combined matrix in the invertible class remains in the same class. © 2015 rafael bru et al.
