D.16.2.9 hilbertBasis

Syntax:

Polymake::hilbertBasis( cone c )

Type:

intmat

Purpose:

intmat, whose rows are the Hilbert basis of the semigroup of lattice points in c.

Note:

the number of elements in the hilbertBasis can be computed through Polymake::nHilbertBasis(c).

Example:

LIB"polymake.lib"; intmat M[3][3]=1,2,-1, 1,-1,2, 1,-1,-1; cone c = coneViaPoints(M); Polymake::hilbertBasis(c);
