This directory contains: Maple programs accompanying the paper: Velleda Baldoni, Nicole Berline, Jesus A. De Loera, Matthias Koeppe, and Michele Vergne, How to integrate a polynomial over a simplex, Mathematics of Computation 80 (2011), no. 273, 297-325, doi:10.1090/S0025-5718-2010-02378-6 The programs are here for archival purposes. They can be used for verifying the computations in this paper. IMPORTANT: For any kind of production use, we recommend to use the software "LattE integrale" instead, which has an implementation of the same algorithms in C++. It is MUCH faster, as demonstrated in the paper: Jesus A. De Loera, Brandon E. Dutra, Matthias Koeppe, Stanislav Moreinis, Gregory Pinto, and Jianqiu Wu, Software for exact integration of polynomials over polyhedra, Computational Geometry: Theory and Applications 46 (2013), no. 3, 232-252, doi:10.1016/j.comgeo.2012.09.001 LattE integrale is available at: https://www.math.ucdavis.edu/~latte/ Matthias Koeppe (for the LattE team)
