Description
|
|
|
•
|
The IsDirected(G) function returns true or false depending on whether the input graph is a directed or undirected graph.
|
|
•
|
The IsWeighted(G) function returns true if G is a weighted graph, and false otherwise.
|
|
•
|
To remove directions and weights from a graph, use the UnderlyingGraph command.
