ndraw

PURPOSE

ndraw(g) --- draw g in a figure window with numbered vertices

SYNOPSIS

function ndraw(g,line_style)

DESCRIPTION

 ndraw(g) --- draw g in a figure window with numbered vertices
 ndraw(g,line_style) --- lines have given line_style
 see also draw, ldraw, and cdraw

CROSS-REFERENCE INFORMATION

This function calls:

• draw draw(g) --- draw g in a figure window
• getxy getxy(g) --- give g's embedding (or [] if g doesn't have one)
• nv nv(g) --- number of vertices in g

This function is called by:

• ldraw ldraw(g,line_style) --- draw a graph with vertices marked with their labels
