EdgeList

EdgeList[g]
gives the list of edges for the graph g.
EdgeList
gives a list of edges that match the pattern patt.
MORE INFORMATION
  • EdgeList returns the list of edges in the order used by the graph g.

Scope   (4)
EdgeList works with undirected graphs:
Directed graphs:
Use a pattern to select a subset of edges:
Works with large graphs:
Applications   (1)
Find all edges with a given property:
Properties & Relations   (5)
EdgeCount can be found using EdgeList:
Edges in EdgeList are given in the same order they are entered for Graph:
Columns of the incidence matrix correspond to EdgeList:
Edges can be explicitly specified in Graph:
A connected graph can be reconstructed from its edge list:
