→Undirected and directed graphs
The unoriented incidence matrix (or simply incidence matrix) of an undirected graph is a matrix B, where n and m are the numbers of vertices and edges respectively, such that if the vertex v<sub>i</sub> and edge e<sub>j</sub> are incident and 0 otherwise.

无向图的无向关联矩阵（或者简单的关联矩阵）是一个矩阵''B''，其中''n''和''m'' 分别是顶点和边的数目，如果顶点 v<sub>i</sub> 和边 e<sub>j</sub>是关联的，则为1，否则为0。
