Error using matlab.graphics.chart.primitive.GraphPlot/highlight>checkEdgesNodePair
显示 更早的评论
I've been trying to add colors to my graph's edges, but I got this error and I have no idea how to solve it:
Error using matlab.graphics.chart.primitive.GraphPlot/highlight>checkEdgesNodePair
s and t must specify edges in the graph.

s = {'a' 'a' 'a' 'a' 'a' 'b' 'b' 'b' 'b' 'c' 'c' 'c' 'd' 'd' 'd' 'e' 'e' 'e' 'e' 'f' 'f' 'f' 'f' 'g' 'g' 'g' 'g' 'g'};
t = {'a' 'b' 'c' 'd' 'f' 'a' 'c' 'd' 'g' 'b' 'c' 'e' 'c' 'a' 'b' 'e' 'c' 'b' 'g' 'a' 'b' 'd' 'e' 'g' 'a' 'c' 'd' 'e'};
G = digraph(s,t)
successors(G, 1)
findedge(G, 1, 6)
There is no edge in G from node 1 to node 6 as you can see from both the successors call and the findedge call.
G.Nodes.Name
You may have intended node 6 to be 'f' but it is 'g' instead. If you want them in that order, say so when you construct the digraph.
G2 = digraph(s, t, [], {'a','b','c','d','e','f','g'})
G2.Nodes.Name
findedge(G2, 1, 6) % There is an edge between 'a' and 'f'

Another option I forgot to mention earlier would be to use node names instead of node indices in your highlight calls.
s = {'a' 'a' 'a' 'a' 'a' 'b' 'b' 'b' 'b' 'c' 'c' 'c' 'd' 'd' 'd' 'e' 'e' 'e' 'e' 'f' 'f' 'f' 'f' 'g' 'g' 'g' 'g' 'g'};
t = {'a' 'b' 'c' 'd' 'f' 'a' 'c' 'd' 'g' 'b' 'c' 'e' 'c' 'a' 'b' 'e' 'c' 'b' 'g' 'a' 'b' 'd' 'e' 'g' 'a' 'c' 'd' 'e'};
G = digraph(s,t);
h = plot(G, 'Layout', 'circle');
highlight(h, ["a", "a"], ["f", "c"])
