Detailed Description

template<class ScalarType>
class Anasazi::HelperTraits< ScalarType >

Class which defines basic traits for working with different scalar types.

An adapter for this traits class must exist for the ScalarType. If not, this class will produce a compile-time error.

template<class ScalarType >
void Anasazi::HelperTraits< ScalarType >::sortRitzValues ( const std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > &  rRV,
const std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > &  iRV,
std::vector< Value< ScalarType > > *  RV,
std::vector< int > *  RO,
std::vector< int > *  RI 
) [static]

Helper function for correctly storing the Ritz values when the eigenproblem is non-Hermitian.

This allows us to use template specialization to compute the right index vector and correctly handle complex-conjugate pairs.

Definition at line 83 of file AnasaziHelperTraits.hpp.

template<class ScalarType >
void Anasazi::HelperTraits< ScalarType >::scaleRitzVectors ( const std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > &  iRV,
Teuchos::SerialDenseMatrix< int, ScalarType > *  S 
) [static]

Helper function for correctly scaling the eigenvectors of the projected eigenproblem.

This allows us to use template specialization to compute the right scaling so the Ritz residuals are correct.

template<class ScalarType >
void Anasazi::HelperTraits< ScalarType >::computeRitzResiduals ( const std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > &  iRV,
const Teuchos::SerialDenseMatrix< int, ScalarType > &  S,
std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > *  RR 
) [static]

Helper function for correctly computing the Ritz residuals of the projected eigenproblem.

This allows us to use template specialization to ensure the Ritz residuals are correct.
