Detailed Description

template<typename ordinal_type, typename value_type>
class Stokhos::SparseGridQuadrature< ordinal_type, value_type >

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

Requires Dakota webbur quadrature package, which is currently provided through TriKota. To enable, configure Stokhos with TriKota enabled and see the TriKota instructions for building TriKota with Dakota.

Constructor & Destructor Documentation

template<typename ordinal_type, typename value_type>

Stokhos::SparseGridQuadrature< ordinal_type, value_type >::SparseGridQuadrature	(	const Teuchos::RCP< const ProductBasis< ordinal_type, value_type > > &	product_basis,
		ordinal_type	sparse_grid_level = 0
	)

Constructor.

Parameters:

	product_basis	product basis
	sparse_grid_level	sparse grid level defining the order of the quadrature. If equal to 0, the level is calculated using a heuristic formula.

const Teuchos::Array< Teuchos::Array< value_type > > & Stokhos::SparseGridQuadrature< ordinal_type, value_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.

Implements Stokhos::Quadrature< ordinal_type, value_type >.

const Teuchos::Array< Teuchos::Array< value_type > > & Stokhos::SparseGridQuadrature< ordinal_type, value_type >::getQuadPoints

(

)

const [virtual]

Get quadrature points.

Array is dimensioned Q-by-d where Q is the number of quadrature points and d is the dimension of the basis.

Implements Stokhos::Quadrature< ordinal_type, value_type >.

template<typename ordinal_type, typename value_type>

const Teuchos::Array< value_type > & Stokhos::SparseGridQuadrature< ordinal_type, value_type >::getQuadWeights

(

)

const [virtual]

Get quadrature weights.

Array is of size Q where Q is the number of quadrature points.

Implements Stokhos::Quadrature< ordinal_type, value_type >.
