For a graph with n Vertices, the n × n matrix A = aij, where the nondiagonal entry aij is the number of edges joining vertex i and Vertex j, and the diagonal entry aii is twice the number of loops at vertex i.
For a diagraph with no loops and not more than one are joining any two Vertices, an n × n matrix A = [aij ], in which aij = 1 if there is an are directed from vertex i to vertex j, and otherwise aij = 0.

The sum of all entries in the adjacency matrix is, of course, the total number of edges in the digraph.
Lou and Hong [19] have considered the distributed surrounding of a convex target set by a group of agents with switching communication graphs and proposed a distributed controller to make the agents surround a given set with equal distance and the desired projection angles specified by a complex-value adjacency matrix.
