example
N= numnodes(G)returns the number of nodes in graphG.
N= numnodes(G)

Use thebuckyadjacency matrix to create a directed graph, and then determine how many nodes the graph contains.
bucky
G = digraph(bucky)
G = digraph with properties: Edges: [180x2 table] Nodes: [60x0 table]
N = 60

Input graph, specified as either agraphordigraphobject. Usegraphto create an undirected graph ordigraphto create a directed graph.
Example:G = graph(1,2)
G = graph(1,2)
Example:G = digraph([1 2],[2 3])
G = digraph([1 2],[2 3])
