MATLAB: How to find all edges indexes if node indexes are given

edgesgraphgraph theorynodes

Hi! How can I find all edges indexes in graph G that are made of nodes 4,5,6 (in this case according to G.Edges those edges are 5 and 6). Can anybody help me with that?

Best Answer

So you're looking for all edges where both end nodes are part of the set 4, 5, 6? This will compute them:
>> [s, t] = findedge(g);
>> nodes = [4 5 6];
>> find(ismember(s, nodes) & ismember(t, nodes))
ans =
     5
     6
