Detailed Description

template<class AdderType>
class Teuchos::MatrixMarket::SymmetrizingAdder< AdderType >

Adds entries with optional symmetry to a sparse matrix.

Author

Mark Hoemmen This class wraps any existing class (AdderType) with the interface shown below. Given the Matrix Market symmetry type, this class' corresponding operator() may invoke AdderType's operator() twice, in order to add entry (j,i) if entry (i,j) is to be added.

Template Parameters

AdderType

A class with at least the following interface: class AdderType { public: typedef ... index_type; // Ellipsis represents the actual type typedef ... value_type; // Ellipsis represents the actual type void operator() (const index_type, const index_type, const value_type&); };

Member Function Documentation

template<class AdderType >

void Teuchos::MatrixMarket::SymmetrizingAdder< AdderType >::operator() ( const index_type  i, const index_type  j, const value_type &  Aij  )

inline

Add value A_ij to entry (i,j), and optionally symmetrize.

Definition at line 135 of file Teuchos_MatrixMarket_SymmetrizingAdder.hpp.

template<class AdderType >

Teuchos::RCP<AdderType> Teuchos::MatrixMarket::SymmetrizingAdder< AdderType >::getAdder ( ) const

inline

Persisting non-const view of the underlying adder object.

This violates encapsulation, so please be careful with this.
