PURPOSE

display(g) --- display basic information about a graph object

SYNOPSIS

function display(g)

DESCRIPTION

 display(g) --- display basic information about a graph object

CROSS-REFERENCE INFORMATION

This function calls:

• isfull isfull(g) --- check if g's adjacency matrix is full
• ne ne(g) --- number of edges in g or ne(g,h) --- check for inequality
• nv nv(g) --- number of vertices in g

This function is called by:

• cayley cayley(g,perms) -- create a Cayley graph (undirected)
