Question on using addedge()

How do we use addedge to assign weights to a graph containing edges with multiple edge weigths(Value1 and Value2, in my example)?
tail = [1 2 3 4];
head = [2 3 4 5];
G = graph(tail,head)
G.Edges.Value1 = ones(4,1)
G.Edges.Value2 = zeros(4,1)
G = addedge(G,5,6,1) %I want to assign 1 to Value1 to the new edge created between nodes 5,6
I obtain the following error.
Error using graph/addedge (line 139)
Unable to add weighted edges to an unweighted graph.
Any suggestions?

Do you mean:
G = addedge(G,5,6)
G.Edges.Value1 = ones(5,1)
Or
T = table(1, 0, 'VariableNames', {'Value1', 'Value2'});
G = addedge(G, 5, 6, T)

Or you can build a table with variables EndNodes and your custom attribute names and call addedge with the graph and the table as the two inputs. The "Add Edges with Attributes to Graph" example on the addedge documentation page shows how to do this.
