**sparse_grid_cc_test**,
a C++ code which
calls sparse_grid_cc(), which
can be used to compute the points and weights of a Smolyak sparse
grid, based on a 1-dimensional Clenshaw-Curtis quadrature rule,
to be used for efficient and accurate quadrature in multiple dimensions.

sparse_grid_cc, a C++ code which creates sparse grids based on Clenshaw-Curtis rules.

- sparse_grid_cc_test.cpp, a sample calling program.
- sparse_grid_cc_test.sh, runs all the tests.
- sparse_grid_cc_test.txt, the output file.

- cc_d2_level3_r.txt, the "R" data for a sparse quadrature rule.
- cc_d2_level3_w.txt, the "W" data for a sparse quadrature rule.
- cc_d2_level3_x.txt, the "X" data for a sparse quadrature rule.
