Graph matrix price weight length
Webmatrix B(G)ofG is the m⇥n matrix whose entries bij are given by bij= (+1 if ej = {vi,vk} for some k 0otherwise. Unlike the case of directed graphs, the entries in the incidence matrix of a graph (undirected) are nonnegative. We usually write B instead of B(G). The notion of adjacency matrix is basically the same for directed or undirected graphs.
