Sufficient Conditions for Generalized Diagonally Dominant Matrices and Block Diagonally Dominant Matrices |
| |
Abstract: | In this paper, we introduce the concept of a-diagonally dominant matrix, and give some new criteria conditions for generalized strictly diagonally dominant matrices ,thus the corresponding results in [1-3]are generalized and improved. |

Keywords: | Generalized diagonal dominant matrices a-diagonal dominant matrix Criteria condition |
