set of edges of graph
list of vertices of graph
(optional) one or more options as specified below
Specifies whether multiple edges should be included in the edges returned. The default value is true.
Specifies whether self-loops should be included in the set of edges returned. The default value is true.
Specifies whether weights should be included in the output. If true, each element of the resulting set is a list whose first element is the edge, and whose second element is the edge weight. The default value is false.
The Edges(G,opts) function returns a collection of the edges of G.
If G is a multigraph, a list is returned. Otherwise, a set is returned.
The Vertices(G) function returns a list of the vertex labels of G.
To count vertices and edges, use the NumberOfEdges or NumberOfVertices commands.
G ≔ Graph⁡1,2,3,4,1,2,1,3,1,4
G≔Graph 1: an undirected graph with 4 vertices and 3 edge(s)
G ≔ Graph⁡a,b,c,a,b,b,c,c,a
G≔Graph 2: a directed graph with 3 vertices and 3 arc(s)
A ≔ Matrix⁡0,1,1,1,0,1,1,1,0:
G ≔ Graph⁡A
G≔Graph 3: an undirected graph with 3 vertices and 3 edge(s)
A ≔ Matrix⁡0.0,0.5,0.0,0.0,0.0,1.0,1.5,0.0,0.0:
G≔Graph 4: a directed weighted graph with 3 vertices and 3 arc(s)
The GraphTheory[Edges] and GraphTheory[Vertices] commands were updated in Maple 2020.
The selfloops option was introduced in Maple 2020.
