sparse

PURPOSE

sparse(g) --- convert internal storage for g to sparse

SYNOPSIS

function sparse(g)

DESCRIPTION

 sparse(g) --- convert internal storage for g to sparse

CROSS-REFERENCE INFORMATION

This function calls:

• sparse sparse(g) --- convert internal storage for g to sparse

This function is called by:

• add add --- add edge(s) to the graph
• bfstree bfstree(t,g,v) --- create a breadth-first spanning tree of g
• clear_edges clear_edges(g) --- delete all edges of g
• disjoint_union disjoint_union(g,h,k) --- overwrite g with the disjoint union of the
• graph graph: constructor for the graph class
• incidence_matrix incidence_matrix(g) --- return the vertex/edge incidence matrix.
• load load(g,filename) --- read a saved graph on disk
• resize resize(g,n) --- change the number of vertices in g to n
• sgf sgf --- simple graph format: a 2-column matrix representation
• shiftgraph shiftgraph(g,k,t) -- create a shiftgraph g based on t-tuples of k symbols
• sl2graph sl2graph(g,p) -- create an SL(2,p) graph
• sparse sparse(g) --- convert internal storage for g to sparse
