摘要
用有向图给出了弱不可约矩阵的一个等价刻划；讨论了弱不可约按回路非零元素链对角占优阵的非异性。
Presents an equivalent description of weak irreducible matrices by means of directed graph and discusses the nonsingularity of weak irreducible diagonal dominant matrices with nonzero element chain according circuit,and gives the corresponging eigenvalues inclusion domain .
