| Abstract: | In this paper,adopted a k-part partition of matrices index set,obtain some new criteria for nonsingular H-matrices,which include and generalize some relative results. Their effectiveness is illustrated by numerical examples. |
| Keywords: | Nonsingular H-matrices generalized strictly diagonally dominant matrices nonzero elements chain irreducibility |
