Computes the affine hull of a polyhedron. This is the affine subspace with the same dimension as the polyhedron, containing the polyhedron.
i1 : P = stdSimplex 3 o1 = {ambient dimension => 4 } dimension of lineality space => 0 dimension of polyhedron => 3 number of facets => 4 number of rays => 0 number of vertices => 4 o1 : Polyhedron |
i2 : Q = affineHull P o2 = {ambient dimension => 4 } dimension of lineality space => 3 dimension of polyhedron => 3 number of facets => 1 number of rays => 0 number of vertices => 1 o2 : Polyhedron |
i3 : linSpace Q o3 = | -1 -1 -1 | | 1 0 0 | | 0 1 0 | | 0 0 1 | 4 3 o3 : Matrix ZZ <--- ZZ |
The object affineHull is a method function.
