get_label

PURPOSE

get_label(g) or get_label(g,v) --- get vertex label(s)

SYNOPSIS

function out = get_label(g,v)

DESCRIPTION

 get_label(g) or get_label(g,v) --- get vertex label(s)
 get_label(g) returns a cell array of the labels of the vertices
 get_label(g,v) returns v's label

CROSS-REFERENCE INFORMATION

This function calls:

• is_labeled is_labeled(g) --- determine if there are labels on vertices.

This function is called by:

• cartesian cartesian(g,h1,h2) --- overwrite g with the product of h1 and h2
• copy_labels copy_labels(g,h) --- copy labels from h to g
• dot dot(g,filename) --- save graph for use by graphviz.
• draw_labels draw_labels(g) --- add labels to a drawing of g
• save save(g,filename) --- save a graph to disk
