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 77 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<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 82 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::X

The current eigenvectors. Definition at line 84 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::KX

The image of the current eigenvectors under K. Definition at line 86 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<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 88 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<const MV> Anasazi::BlockDavidsonState< ScalarType, MV >::R

The current residual vectors. Definition at line 90 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<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 95 of file AnasaziBlockDavidson.hpp.

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

The current Ritz values. Definition at line 97 of file AnasaziBlockDavidson.hpp.

template<class ScalarType, class MV> Teuchos::RefCountPtr<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. Definition at line 103 of file AnasaziBlockDavidson.hpp.
