For example, we have a graph below. An undirected graph We can represent this graph in matrix form like below. Matrix representation of the graph Each cell in the above table/matrix is represented asAij, whereia
example A= adjacency(G,'weighted')returns a weighted adjacency matrix, where for each edge(i,j), the valueA(i,j)contains the weight of the edge. If the graph has no edge weights, thenA(i,j)is set to 1. For this syntax,Gmust be a simple graph such thatismultigraph(G)returnsfalse...

Adjacency matrixEigenvaluesSpectral radiusWe obtain bounds for the largest and least eigenvalues of the adjacency matrix of a simple undirected graph. We find upper bound for the second largest eigenvalue of the adjacency matrix. We prove that the bounds obtained here improve on the existing bounds...
Example 1 The adjacency matrices for the two graphs in Figure 8.1 and the two digraphs in Figure 8.2 are as follows: The adjacency matrix of any graph is symmetric, for the obvious reason that there is an edge between Pi and Pj if and only if there is an edge (the same one) between...

The main diagonal of every adjacency matrix corresponding to a graph without loops has all zero entries. Note that here 'loops' means, for example A->A, not 'cycles' such as A->B->A. For[Math Processing Error] -regular graphs, d is also an eigenvalue of A for the vector [Math Pr...
