How can I check if any two nodes in an undirected graph are connected via an edge or not, please? in other words, Are they neighbors or not? Thanks!

Call findedge(g, node1, node2). If there is no edge connecting these nodes, the output is zero. Otherwise, the output is the index into the Edges table of the connecting edge.
