LattE (Lattice point Enumeration) is a computer software dedicated to the
problems of counting lattice points and integration inside convex polytopes.
LattE contains the first ever implementation of Barvinok's algorithm. The
LattE macchiato version (by M. Köppe) incorporated fundamental improvements
and speed ups. Now the latest version, LattE integrale, has the ability to
directly compute integrals of polynomial functions over polytopes and in
particular to do volume computations.
