graph_complement — complement of a graph
g1 = graph_complement(g,[gmax])
graph_complement returns the undirected graph g1 which is the complement of the graph g with respect to the corresponding complete graph. When gmax is given, the complement is made with respect to gmax. g and gmax are supposed to be simple graphs (use graph_simp before calling graph_complement if necessary) and to have the same number of nodes.
