| Abstract: | The positive definiteness(semi-definiteness)matrix,the generalized positive definiteness(semi-definiteness)matrix,the generalized positive the generalized diagonalliy dominant matrix and M-matrix are widely used in the fields like automatic control theory,neural network computing, robot,etc,It is of great importance to make a criterion of them.Based on the existing criteria,more practical theoermes are given in this article. |
