Fig. 1. Networks and Adjacency Matrices.
(A) Network (B) Adjacency Matrix, respective entries in the adjacency matrix indicate the edge weight of an edge that is between nodes which are given by the respective row/column pairs. A weight of zero indicates the absence of an edge, while in an unweighted network the default edge weight is 1. (C) Bipartite Network (D) Adjacency matrix for bipartite network.
