WebDescription. H = addedge (G,s,t) adds an edge to graph G between nodes s and t. If a node specified by s or t is not present in G, then that node is added. The new graph, H, is equivalent to G , but includes the new edge and any required new nodes. H = addedge (G,s,t,w) also specifies weights, w, for the edges between s and t.
