Hi, I am working on the shortest path problem and I want to be able to display the total weights between 2 points in the command window. I've been able to display the route it has taken but I want it to display the weights of the edges as well
Thanks

If you're using a graph or digraph and want to find the Weight for a particular edge, look at the Edges table, possibly in conjunction with findedge. Using the digraph created on this page with the Weights:
s = [1 1 2 2 3];
t = [2 4 3 4 4];
G = digraph(s,t);
G.Edges.Weight = [10 20 30 40 50]';
G
G.Edges
I can extract the weights of the edge between 1 and 4 with either of these lines:
G.Edges.Weight(findedge(G, 1, 4))
G.Edges{findedge(G, 1, 4), 'Weight'}
Of course, the shortestpath method gives you the edge IDs, so you don't need to use findedge here. Since edge (1, 4) is the second edge:
G.Edges{2, 'Weight'}

The second and third examples on the documentation page for shortestpath to which I linked in my answer show how to do that. The third example also includes a call to highlight to show the path, as you did in your comment from about two hours ago.
