**nint_exactness_test**,
a MATLAB program which
calls nint_exactness_test() to investigate the polynomial exactness of a multidimensional
quadrature rule based on a direct product of one-dimensional rules.

nint_exactness_mixed, a MATLAB program which measures the monomial exactness of an M-dimensional quadrature rule based on a mixture of 1D quadrature rule factors.

- nint_exactness_mixed_test.m, calls all the tests.
- nint_exactness_mixed_test.sh, runs all the tests.
- nint_exactness_mixed_test.txt, the output file.

**SPARSE_GRID_MIXED_D2_L2_CCXGL** is a level 2 sparse grid quadrature rule for
dimension 2, based on 1D factors of [Clenshaw Curtis, Gauss Legendre].
