MakeDirected(G)

MakeDirected(G, M)

Parameters

G

-

undirected graph

M

-

(optional) Matrix

Description

• 

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.
