PURPOSE

copy_labels(g,h) --- copy labels from h to g

SYNOPSIS

function copy_labels(g,h)

DESCRIPTION

 copy_labels(g,h) --- copy labels from h to g

CROSS-REFERENCE INFORMATION

This function calls:

• get_label get_label(g) or get_label(g,v) --- get vertex label(s)
• is_labeled is_labeled(g) --- determine if there are labels on vertices.
• label Assign labels to vertices of g
• nv nv(g) --- number of vertices in g

This function is called by:

• bfstree bfstree(t,g,v) --- create a breadth-first spanning tree of g
• dfstree dfstree(t,g,v) --- create a depth-first spanning tree of g

SOURCE CODE

0005     error('Source graph (2nd argument) must be labeled')
0006 end
0007 
0008 ng = nv(g);
0009 nh = nv(h);
