Undirected adjacency matrix
WebAdjacency Matrix. The adjacency matrix of a simple labeled graph is the matrix A with A [ [i,j]] or 0 according to whether the vertex vj, is adjacent to the vertex vj or not. For simple graphs without self-loops, the adjacency matrix has 0 s on the diagonal. For undirected graphs, the adjacency matrix is symmetric. #include
