Incidence structures may be represented in many ways. If the sets P and L are finite these representations can compactly encode all the relevant information concerning the structure. The incidence matrix of a (finite) incidence structure is a (0,1) matrix that has its rows indexed by the points {pi} and columns indexed by the lines {lj} where the ij-th entry is a 1 if pi I lj and 0 otherwise. An incidence matrix is not uniquely determined since it depends upon the arbitrary or… WebIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph.
