Polyhedra :: isReflexive

isReflexive -- checks if a Polytope is reflexive

Synopsis

Description

A lattice polytope P in the QQ space of a lattice M is reflexive if its polar polytope is also a lattice polytope. The function checks if P is compact, a lattice polytope and if the dual is a lattice polytope.

i1 : P = convexHull matrix {{1,0,-1},{0,1,-1}}

o1 = P

o1 : Polyhedron
i2 : isReflexive P

o2 = true
