**power_rule_test**,
a C++ code which
calls power_rule(), which
creates a power rule, that is, a multidimensional quadrature rule
formed as a repeated product of a single one-dimensional quadrature rule.

power_rule, a C++ code which constructs a power rule, that is, a product quadrature rule from identical 1D factor rules.

- power_rule_test.sh, runs all the tests.
- power_rule_test.txt, the output file.

- cc3_x.txt, the abscissas of a 1D Clenshaw Curtis rule of order 3.
- cc3_w.txt, the weights of a 1D Clenshaw Curtis rule of order 3.
- cc3_r.txt, defines the range of the region.

We give the command

to create a Clenshaw Curtis product rule of order 3x3 for a 2D region. The files which are created include:power_rulecc3 2

- power_x.txt, the abscissas of the power rule.
- power_w.txt, the weights of the power rule.
- power_r.txt, defines the range of the power region.
