networks

 vweight
 finds vertex weights in a graph

 Calling Sequence vweight(G) vweight(v, G) vweight(vlist, G)

Parameters

 G - graph or network v - vertex or list of vertices vlist - vertex or list of vertices

Description

 • Important: The networks package has been deprecated.Use the superseding package GraphTheory instead.
 • Given just the graph G the vertex weight table of the graph is returned. This is part of the internal data-structure of the graph and so changes to it affect the graph itself.
 • If a vertex is provided as the first argument then the weight of vlist is returned while if a list vlist of vertices is provided then a list of weights is returned.
 • Vertex weights are ordinarily 0 unless explicitly set to some other value by assignment to the weight table.  They may be assigned any valid maple object.
 • This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[vweight](...).
