%% Adjacency Matrix of Weighted Graph % Create an undirected graph using an upper triangular adjacency matrix. % When constructing a graph with an adjacency matrix, the nonzero values in % the matrix correspond to edge weights. % Copyright 2015 The MathWorks, Inc. A = [0 5 3 0;0 0 1 2; 0 0 0 11; 0 0 0 0] %% % G = graph(A,'upper') %% % G.Edges %% % Use |adjacency| to return the adjacency matrix of the graph. Regardless % of the form of adjacency matrix used to construct the graph, the % |adjacency| function always returns a symmetric and sparse adjacency % matrix containing only 1s and 0s. B = adjacency(G)
