If a graph has vertices, we may associate an matrix which is called vertex matrix or adjacency matrix. Recall that a permutation matrix is a square matrix whose entries are all 0 0 0 or 1, 1, 1, such that each row and each column contains exactly one 1. This matrix can be used to obtain more detailed information about the graph. ![]() ![]() For an easy graph with no self-loops, the adjacency matrix must have 0s on the diagonal. ![]() The n x n matrix A, in which a ij 1 if there exists a path from v i to v j a ij 0 otherwise is called an adjacency matrix. The adjacency matrix, sometimes also referred to as the connection matrix, of an easy labeled graph may be a matrix with rows and columns labeled by graph vertices, with a 1 or 0 in position consistent with whether and. Given a graph G G G with n n n vertices, the adjacency matrix is an n × n n \times n n × n matrixĪ = ( a 11 a 12 ⋯ a 1 n a 21 a 22 ⋯ a 2 n ⋮ ⋮ ⋱ ⋮ a n 1 a n 2 ⋯ a n n ) ,Ī = \begin. An adjacency matrix is defined as follows: Let G be a graph with 'n' vertices that are assumed to be ordered from v 1 to v n.
