Hamming index of some thorn graphs with respect to adjacency matrix.

Let G be a graph with vertex set V(G) = {v1,v2,..., vn}. Let A(G) be the adjacency matrix of a graph G. The rows of A(G) corresponding to a vertex v of G, denoted by s(v) is the string. The Hamming index of a graph G is the sum of the Hamming distances between all pairs of vertices of G. In this paper we obtain Hamming index generated by adjacency matrix of some thorn graphs.
