I have a 20*20 symmetric matrix that represents connections between 20 nodes in a random graph. In this matrix all the diagonal elements are zero which means there is no self loop for any nodes. Also the non-diagonal elements are selected randomly from {0,1,2,3}. Let a (i,j) be the element of this matrix which represents edge between …

WebThe adjacency matrix of a graph provides a method of counting these paths by calcu-lating the powers of the matrices. Theorem 2.1. Let Gbe a graph with adjacency matrix Aand kbe a positive integer. Then the matrix power Ak gives the matrix where A ij counts the the number of paths of length k between vertices v i and v j.
