 DrawNetwork

 Calling Sequence DrawNetwork(G) DrawNetwork(G, st) DrawNetwork(G, S, T) DrawNetwork(G, S, T, st)

Parameters

 G - graph st - (optional) 'horizontal', 'vertical' S - (optional) vertex T - (optional) vertex

Description

 • DrawNetwork displays the vertices, arcs and vertex labels of a network. A network is a directed graph with at least one vertex with indegree 0 (the source) and at least one vertex with outdegree 0 (the sink).
 • If you specify S and T, the graph is displayed with S as the main source and T as the main sink.
 • The network can be displayed either horizontally or vertically.
 • Remaining options are passed on to the DrawGraph command.
