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.

Member Function Documentation

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.

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.
