**power_rule_rest**,
a FORTRAN90 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 FORTRAN90 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.

As an example, we start with a 1D Clenshaw Curtis rule of order 3:

- 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.

The files which are created include:

- power_rule.txt, the output file.
- 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.
