numedges

Number of edges in graph

Syntax

N = numedges(G)

N = numedges(G) returns the number of edges in graph G.

Use the bucky adjacency matrix to create a directed graph, and then determine how many edges the graph contains.

G = digraph(bucky)

G = 
  digraph with properties:

    Edges: [180x2 table]
    Nodes: [60x0 table]

N = numedges(G)

N = 180

Input graph, specified as either a graph or digraph object. Use graph to create an undirected graph or digraph to create a directed graph.

Example: G = graph(1,2)

Example: G = digraph([1 2],[2 3])

Number of edges, returned as a scalar.
