D.16.2.14 isCanonical

Syntax:

Polymake::isCanonical( polytope p )

Type:

int

Purpose:

1 if p has exactly one interior lattice point, 0 otherwise.

Example:

LIB"polymake.lib"; intmat M[6][4]=1,1,1,2, 1,-1,-1,-2, 1,1,0,0, 1,-1,0,0, 1,0,1,0, 1,0,-1,0; polytope p = polytopeViaPoints(M); Polymake::isCanonical(p); Polymake::isReflexive(p); intmat N[3][3]=1,2,0, 1,0,2, 1,-2,-2; polytope q = polytopeViaPoints(N); Polymake::isCanonical(q);
