In terms of the adjacency matrix, a disconnected graph means that you can permute the rows and columns of this matrix in a way where the new matrix is block-diagonal with two or more blocks (the maximum number of diagonal blocks corresponds to the number of connected components). If you want to compute this from …

• A permutation matrix is a (0, 1)-matrix, all of whose columns and rows each have exactly one nonzero element. • An incidence matrix in combinatorics and finite geometry has ones to indicate incidence between points (or vertices) and lines of a geometry, blocks of a block design, or edges of a graph. WebLet N be the set of n elements {1, 2, … , n} and E a binary relation: E ⊆ N × N, also denoted by an arrow, →. Consider N to be the set of nodes of a directed graph G, and E the set of arcs (directed edges). A directed graph G may be represented by its adjacency matrix A (Fig. 11.1), an n × n boolean matrix whose
