getxy

PURPOSE

getxy(g) --- give g's embedding (or [] if g doesn't have one)

SYNOPSIS

function z = getxy(g)

DESCRIPTION

 getxy(g) --- give g's embedding (or [] if g doesn't have one)

CROSS-REFERENCE INFORMATION

This function calls:

• hasxy hasxy(g) --- determine if an embedding has been created for g

This function is called by:

• bfstree bfstree(t,g,v) --- create a breadth-first spanning tree of g
• cartesian cartesian(g,h1,h2) --- overwrite g with the product of h1 and h2
• cdraw cdraw(g,coloring) -- draw g with a given vertex coloring
• dfstree dfstree(t,g,v) --- create a depth-first spanning tree of g
• disjoint_union disjoint_union(g,h,k) --- overwrite g with the disjoint union of the
• distxy distxy(g) -- give g a distance based embedding
• draw draw(g) --- draw g in a figure window
• draw_labels draw_labels(g) --- add labels to a drawing of g
• graffle graffle(g, filename, width, rad) --- write graph in OmniGraffle format
• induce induce --- create induced subgraphs
• join join(g,h1,h2) --- overwrite g with the join of h1 and h2
• line_graph line_graph(g,h) --- set g to be the line graph of h
• ndraw ndraw(g) --- draw g in a figure window with numbered vertices
• renumber renumber the vertices of a graph
• save save(g,filename) --- save a graph to disk
• scale scale(g,s) --- rescale the embedding of g by s
• sgf sgf --- simple graph format: a 2-column matrix representation
• springxy springxy(g) --- find a spring embedding of g
