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.

const Teuchos::Array< Teuchos::Array< value_type > > & Stokhos::SmolyakSparseGridQuadrature< ordinal_type, value_type, point_compare_type >::getBasisAtQuadPoints ( ) const

virtual

Get values of basis at quadrature points.

Array is dimensioned Q-by-P where Q is the number of quadrature points and P is the size of the basis.
