MakeDirected(G)
MakeDirected(G, M)
G
-
undirected graph
M
(optional) Matrix
The MakeDirected command returns a directed graph with vertices from G. For each edge in G, the arcs in both directions are in the new graph. If G is a weighted graph, then a matrix M may be included as part of the input; in such a case the arc weights are taken from the entries of M.
