摘要
将矩阵进行特殊分块,结合schur-补矩阵的性质,得到了非负矩阵是逆M-矩阵的充要条件;进一步结合周期三对角矩阵的性质和三对角逆M-矩阵的充要条件,得到了周期三对角逆M-矩阵的充要条件.
Partitioning specially and using the properties of schur compelements sufficient conditions for inverse M-matrices; the properties of tri-diagonal period sary and suflqcient conditions for the tri-diagonal matrices are combined, and the of the tri-diagonal period inverse M-matrices are obtained. matrices, it gets the necessary and inverse M-matrices and the necesnecessary and sufficient conditions
