WebMar 16, 2024 · Introduction: A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (V, E). Webmultigraph or a weighted graph, then A ij is equal to the number of edges between (i;j), or the weight of the edge (i;j), respectively. The adjacency matrix of an undirected graph is symmetric, and this implies that its eigenvalues are all real. De nition 1 A matrix M2C n is Hermitian if M ij = M ji for every i;j.
