normaliz

Normaliz is a tool for computations in affine monoids, vector configurations,
lattice polytopes, and rational cones. It supports,

convex hulls and dual cones
conversion from generators to constraints and vice versa
triangulations, disjoint decompositions and Stanley decompositions
Hilbert basis of rational, not necessarily pointed cones
normalization of affine monoids
lattice points of rational polytopes and (unbounded) polyhedra
Hilbert (or Ehrhart) series and (quasi) polynomials under
Z-gradings (for example, for rational polytopes)
generalized (or weighted) Ehrhart series and Lebesgue integrals of
polynomials over rational polytopes via NmzIntegrate
