Parameters

Description

Examples

Calling Sequence

IncidentEdges(G, V, d)

Parameters

G

-

graph or digraph

V

-

vertex or list of vertices

d

-

(optional) equation of the form direction=incoming or outgoing

Description

• 

IncidentEdges returns the set of edges (arcs) which are incident to a given vertices.  If G is a directed graph, then the set of arcs which have a tail in the given list of vertices are returned.

• 

IncidentEdges(G, V, direction=incoming) returns the set of arcs which have a head in the given set of vertices.
