So with the adjacency matrix that has n vertices of a directed graph n2 units needed to store the adjacency matrix; on n vertices have an undirected graph Zexu into upper triangle, and only ...

因此用邻接矩阵来表示一个具有n个顶点的有向图时需要n2个单位来存储邻接矩阵；对有n个顶点的无向图则需存入上三角形，故只。。。

Firstly, we give a necessary and sufficient condition for a nonnegative square matrix to be decomposed into a product of a finite number of irreducible nonnegative matrices in chapter 1. We prove it by using Frobenius normal form in combinational matrix theory and associated directed graph in graph theory. In addition, we can limit the number of factors to three, and construct every factor.
