size
PURPOSE 
size(g) --- returns [nv,ne] for the graph
SYNOPSIS 
function [sz,tz] = size(g)
DESCRIPTION 
CROSS-REFERENCE INFORMATION 
This function calls:
- 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:
- add add --- add edge(s) to the graph
- alpha [a,S] = alpha(g) --- indepencence number
- cayley cayley(g,perms) -- create a Cayley graph (undirected)
- cdraw cdraw(g,coloring) -- draw g with a given vertex coloring
- chromatic_poly chrompoly(g) --- find the chromatic polynomial of g
- delete delete --- delete vertices or edges from a graph
- distxy distxy(g) -- give g a distance based embedding
- embed embed --- create an embedding for a graph
- eq yn = eq(g,h) --- check if two graphs are equal (identical)
- graph graph: constructor for the graph class
- hasxy hasxy(g) --- determine if an embedding has been created for g
- incidence_matrix incidence_matrix(g) --- return the vertex/edge incidence matrix.
- interval_graph interval_graph(g,ilist) --- create an interval graph
- iso [yn,p] = iso(g,h,options) --- is g isomorphic to h?
- line_graph line_graph(g,h) --- set g to be the line graph of h
- ne ne(g) --- number of edges in g or ne(g,h) --- check for inequality
- random_planar random_planar(g,n) --- create a random planar triangulation
- sgf sgf --- simple graph format: a 2-column matrix representation
- sl2graph sl2graph(g,p) -- create an SL(2,p) graph
