%% Distances of Nearest Nodes % Create and plot a graph with weighted edges. s = [1 1 1 2 2 6 6 7 7 3 3 9 9 4 4 11 11 8]; t = [2 3 4 5 6 7 8 5 8 9 10 5 10 11 12 10 12 12]; weights = [10 10 10 10 10 1 1 1 1 1 1 1 1 1 1 1 1 1]; G = graph(s,t,weights); plot(G,'EdgeLabel',G.Edges.Weight) %% % Determine which nodes are within a radius of 5 from node 3, and return % the distance to each node. [nn,dist] = nearest(G,3,5)
