UndirectedGraph

UndirectedGraph[g]
gives an undirected graph from the directed graph g.
MORE INFORMATION
  • The undirected edge is an edge in the resulting undirected graph if either of the directed edges or is an edge of g.

UndirectedGraph works with directed graphs:
Directed edges with different directions convert to one undirected edge:
Works with large graphs:
Properties & Relations   (4)
An undirected graph can be constructed by a list of UndirectedEdge objects:
A graph is either undirected or directed:
A symmetric adjacency matrix is interpreted to be an undirected graph:
Use DirectedEdges->True to interpret it as a directed graph:
The incidence matrix of an undirected graph has no negative entries:
