make graph directed
(optional) one or more options as specified below
root = vertex of G
In the case when G is a tree, specifies a root vertex for an arborescence with all undirected edges in G converted to directed edges heading away from root.
totalorder = list of vertices
Specifies a total ordering for the vertices. When this option is provided, an undirected edge between vertices a and b is transformed to a single directed edge based on the total order.
The MakeDirected command returns a directed graph with vertices from G.
By default, 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.

The GraphTheory[MakeDirected] command was updated in Maple 2021.
