An adjacency matrix is a way of representing a graph as a matrix of booleans (0's and 1's). AB = BA 2. For the example, students were asked to name up to five other students in their class that they considered to be friends.
The classical adjoint, or adjugate, of a square matrix A is the square matrix X, such that the ( i, j )-th entry of X is the ( j, i )-th cofactor of A. For a 2 x 2 matrix the minor of each position M [r,c] is the diagonally opposite element. But if the graph is dense then the number of edges is close to (the complete) n ( n − 1) / 2, or to n 2 if the graph is directed with self-loops. (If there were two loops for node 1, the entry would be 2.
