Detailed Description

template<class ScalarType, class MV>
struct Anasazi::BlockDavidsonState< ScalarType, MV >

Structure to contain pointers to BlockDavidson state variables.

This struct is utilized by BlockDavidson::initialize() and BlockDavidson::getState().

Member Data Documentation

template<class ScalarType, class MV>

int Anasazi::BlockDavidsonState< ScalarType, MV >::curDim

The current dimension of the solver.

This should always be equal to BlockDavdison::getCurSubspaceDim()

Definition at line 95 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::V

The basis for the Krylov space.

V has BlockDavidson::getMaxSubspaceDim() vectors, but only the first curDim are valid.

Definition at line 100 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::X

The current eigenvectors.

Definition at line 102 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::KX

The image of the current eigenvectors under K.

Definition at line 104 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::MX

The image of the current eigenvectors under M, or Teuchos::null if M was not specified.

Definition at line 106 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::R

The current residual vectors.

Definition at line 108 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::H

The current preconditioned residual vectors.

H is a pointer into V, and is only useful when BlockDavidson::iterate() throw a BlockDavidsonOrthoFailure exception.

Definition at line 113 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const std::vector<typename Teuchos::ScalarTraits<ScalarType>::magnitudeType> > Anasazi::BlockDavidsonState< ScalarType, MV >::T

The current Ritz values. This vector is a copy of the internal data.

Definition at line 115 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV>

Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > Anasazi::BlockDavidsonState< ScalarType, MV >::KK

The current projected K matrix.

KK is of order BlockDavidson::getMaxSubspaceDim(), but only the principal submatrix of order curDim is meaningful. It is Hermitian in memory.
