Detailed Description

template<typename ordinal_type, typename value_type, typename point_compare_type = typename DefaultPointCompare<ordinal_type,value_type>::type>
class Stokhos::SmolyakSparseGridQuadrature< ordinal_type, value_type, point_compare_type >

Defines quadrature for a tensor product basis by Smolyak sparse grids.

This class generates the sparse grids using the SmolyakPseudoSpectralOperator and doesn't rely on Dakota.
