cc_display, an Octave code which displays the abscissas used in a 2D Clenshaw-Curtis quadrature rule.
The current version only considers a single Clenshaw Curtis grid, in which the orders of the rule in the X and Y directions may differ.
Variations could be added, in which the points associated with an isotropic Smolyak rule would be displayed, or in which several sets of Clenshaw Curtis grids would be superimposed, or a Gauss-Legendre rule would be displayed.
