Polyhedra :: sublatticeBasis

sublatticeBasis -- computes a basis for the sublattice generated by integral vectors or lattice points of a polytope

Synopsis

Description

sublatticeBasis computes a basis for the sublattice generated by the columns ofM or by the lattice points ofP.

i1 : P = convexHull transpose matrix {{0,0,0},{1,0,0},{0,1,0},{1,1,3}}

o1 = P

o1 : Polyhedron
i2 : sublatticeBasis P

o2 = | 1 0 1 |
     | 0 1 1 |
     | 0 0 3 |

              3        3
o2 : Matrix ZZ  <--- ZZ
