power_rule, a C code which constructs a power rule, that is, a product quadrature rule from identical 1D factor rules.
As an example, we start with a 1D Clenshaw Curtis rule of order 3:
We give the command
power_rule cc3 2to create a Clenshaw Curtis product rule of order 9 for a 2D region. The files which are created include:
