18 March 2020 10:23:11 AM HYPERCUBE_EXACTNESS C++ version Investigate the polynomial exactness of a quadrature rule by integrating all monomials of a given degree over the [0,1] hypercube. The rule will be adjusted to the [0,1] hypercube. HYPERCUBE_EXACTNESS: User input: Quadrature rule X file = "cce_d2_level2_x.txt". Quadrature rule W file = "cce_d2_level2_w.txt". Quadrature rule R file = "cce_d2_level2_r.txt".
