sparse_grid_total_poly, a MATLAB code which investigates the efficient approximation of all polynomials up to a given total degree using sparse grids.

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

- point_quality_test.m computes the point quality for quadrature rules.
- rule_test.m tests a rule simply by printing out some examples of it.
- rules_test.m calls RULE_TEST for each of the rules.
- weight_quality_test.m computes the weight quality for quadrature rules.
