摘要：
In this paper, according to the theory of two classes of a-diagonally dominant matrices, the row index set of the matrix is divided properly, and then some positive diagonal matrices are constructed. Furthermore, some new criteria for nonsingular H-matrix are obtained. Finally, numerical examples are given to illustrate the effectiveness of the proposed criteria.
