In the subject of graph theory, a graph is just a collection of vertices and some edges connecting vertices. A matrix can be used to indicate how many edges attach one vertex to another. For example, the graph pictured above would have the following matrix, where mi j indicates the number of edges between the vertices labeled i and j: M =  1 2 1 1 2 0 1 0 1 1 0 1 1 0 1 3  This is an example of a symmetric matrix, since mi j = m j i .
