| Abstract: |
| Some sufficient conditions for a matrix to be a quasi-diagonally dominant matrix and some criteria for a matrix to be a nonsingular M-matrix are obtained.The known results in the relevant reference were improved and generalized by these results. |
| Key words: quasi-diagonally dominant matrix nonsingular M-matrix matrices circuit |
