FullGridQuadraticSummationStrategy()

template<typename V>

sgpp::combigrid::FullGridQuadraticSummationStrategy< V >::FullGridQuadraticSummationStrategy ( std::shared_ptr< AbstractCombigridStorage >  storage, std::vector< std::shared_ptr< AbstractLinearEvaluator< V >>>  evaluatorPrototypes, std::vector< std::shared_ptr< AbstractPointHierarchy >>  pointHierarchies  )

inline

Constructor.

Parameters

storage	Storage that stores and provides the function values for each grid point.
evaluatorPrototypes	prototype objects for the evaluators that are cloned to get an evaluator for each dimension and each level.
pointHierarchies	PointHierarchy objects for each dimension providing the points for each level and information about their ordering.

eval()

template<typename V>

V sgpp::combigrid::FullGridQuadraticSummationStrategy< V >::eval ( MultiIndex const &  level )

inlineoverridevirtual

Evaluates the function given through the storage for a certain level-multi-index (see class description).

Summation of the form \(\sum_i coefficients_i \sum_j coefficients_j basis_i(param) basis_j(param) \Leftrightarrow v^T * A * v, A_ij = < basis_i(param),basis_j(param) >, v_i = coefficients_i \). This is used for variance calculations. Currently it can only be used with template type V = FloatArrayVector

Implements sgpp::combigrid::AbstractFullGridSummationStrategy< V >.
