SYNOPSIS

function make_logical(g)

DESCRIPTION

 make_logical(g) --- ensure that the internal storage for g's matrix is a
 logical matrix (for space efficiency). 
 This function is called by various matgraph routines and it should not 
 be necessary to call this in ordinary use of matgraph.

CROSS-REFERENCE INFORMATION

This function calls:

This function is called by:

• disjoint_union disjoint_union(g,h,k) --- overwrite g with the disjoint union of the
• graph graph: constructor for the graph class
• renumber renumber the vertices of a graph
• resize resize(g,n) --- change the number of vertices in g to n
