图与矩阵运算

Graph and Matrix Operation

提出了与已有的利用Ｃｏａｔｅｓ图及Ｍａｓｏｎ图处理线性系统不同的作法，以图论解释每个矩阵及矩阵运算，并给出了求可逆矩阵的逆矩阵的图上操作方案。

Different from using Coates graph or Mason graph to treat linear systems.this note develops a method,which gives graph-theoretic explanation to each matrix as well as to each matrix operation,especially,one can find the inverse of matrix by means of operating on graphs.
