product_rule, a C++ code which constructs a product quadrature rule from distinct 1D factor rules.
As an example, we make a 2D product rule.
The first factor is a 1D Clenshaw Curtis rule of order 3:
The second factor is a 1D Gauss Legendre rule of order 2:
We give the command
The resulting product rule files:
