Use thebuckyadjacency matrix to create a directed graph, and then determine how many nodes the graph contains.

G = digraph(bucky)

G = digraph with properties: Edges: [180x2 table] Nodes: [60x0 table]

N = numnodes(G)

N = 60

Input graph, specified as either agraphordigraphobject. Usegraphto create an undirected graph ordigraphto create a directed graph.

Example:G = graph(1,2)

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