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

Use the bucky adjacency 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
graph
digraph
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)
G = graph(1,2)
Example: G = digraph([1 2],[2 3])
G = digraph([1 2],[2 3])
Number of nodes, returned as a scalar.
