neighboring vertices found along outgoing edges
vertex of G
graph or network
Important: The networks package has been deprecated. Use the superseding command GraphTheory[Departures] instead.
Given a vertex v of a graph G, this routine returns the set of vertices which are at the head of edges directed out of v.
Undirected edges are treated as if they were bidirectional.
The arrivals and departure information is constructed from the neighbors table which is automatically maintained by the graph primitives such as addedge() and delete().
When no vertices are specified a departures table, indexed by vertices, is constructed. This table is not part of the graph data structure so that the graph remains unaffected by assignments to the table.
This routine is normally loaded using the command with(networks) but may also be referenced using the full name networks[departures](...).
