WebEvidently, since matrix is square, directed edge between all vertex pairs has a corresponding edge symmetric to it, coded in the matrix and thus this matrix can be interpreted as an adjacency matrix of some graph. Furthermore, since there are only zeros on the diagonal, no edge connects a vertex to itself and thus there are no loops. Spectrum The adjacency matrix of an undirected simple graph is symmetric, and therefore has a complete set of real eigenvalues and an orthogonal eigenvector basis. The set of eigenvalues of a graph is the spectrum of the graph. It is common to denote the eigenvalues by $${\displaystyle \lambda _{1}\geq … See more In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case … See more The adjacency matrix may be used as a data structure for the representation of graphs in computer programs for manipulating graphs.
