SPARSE_GRID_GLO
Gauss-Legendre Linear (Odd) Growth Sparse Grids

SPARSE_GRID_GLO is a dataset directory which contains files definining sparse grids based on the 1D Gauss-Legendre rule with linear (odd) growth.

Each sparse grid is stored using the "quadrature rule" format, that is, as three files:

• an "R" or "region" file, which lists two points that bound the region;
• a "W" or "weight" file, which lists the weight for each abscissa;
• an "X" or "abscissa" file, which lists the abscissas of the rule.
