摘要
给出了非奇M -矩阵新的判定定理.利用矩阵B=A +AT 满足新的判定定理的条件 ,得出矩阵A为非奇M矩阵的结论 ,推广了已有的判定定理.实例说明 。
Some new judging criterions for non-singular M-matrices are presented by using the matrixB=A+AT. It satisfies the new judging conditions and generalized the concluded results.By using the given theorems,as the example illustrated,the determinate results can be more conveniently obtained.
