%% Highlight Minimum Spanning Tree of Graph % Create and plot a graph. Return a handle to the |GraphPlot| object, |h|. % Copyright 2015 The MathWorks, Inc. s = [1 1 1 1 1 1 2 3 4 5 6 7 7 7 7 8 9 10 11 8 6]; t = [2 3 4 5 6 7 3 4 5 6 2 8 9 10 11 10 10 11 8 1 11]; G = graph(s,t); h = plot(G) %% % Calculate the minimum spanning tree of the graph. Highlight the minimum % spanning tree subgraph in the plot by increasing the line width and % changing the color of the edges in the tree. [T,p] = minspantree(G); highlight(h,T,'EdgeColor','r','LineWidth',1.5)
