Adjacency matrix - Wikipedia

If A is the adjacency matrix of the directed or undirected graph G, then the matrix A

If A is the adjacency matrix of the directed or undirected graph G, then the matrix A

^{n}(i.e. the matrix product of n copies of A) has an interesting interpretation: the entry in row i and column j gives the number of (directed or undirected) paths of length n from vertex i to vertex j.## Thursday, November 06, 2003
