Member Data Documentation

template<class ScalarType, class MV>
int Belos::PseudoBlockGmresIterState< ScalarType, MV >::curDim

The current dimension of the reduction.

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

Definition at line 67 of file BelosPseudoBlockGmresIter.hpp.

template<class ScalarType, class MV>
std::vector<Teuchos::RCP<const MV> > Belos::PseudoBlockGmresIterState< ScalarType, MV >::V

The current Krylov basis.

template<class ScalarType, class MV>
std::vector<Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > > Belos::PseudoBlockGmresIterState< ScalarType, MV >::H

The current Hessenberg matrix.

The curDim by curDim leading submatrix of H is the projection of problem->getOperator() by the first curDim vectors in V.

Definition at line 75 of file BelosPseudoBlockGmresIter.hpp.

template<class ScalarType, class MV>
std::vector<Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > > Belos::PseudoBlockGmresIterState< ScalarType, MV >::R

The current upper-triangular matrix from the QR reduction of H.

Definition at line 77 of file BelosPseudoBlockGmresIter.hpp.

template<class ScalarType, class MV>
std::vector<Teuchos::RCP<const Teuchos::SerialDenseVector<int,ScalarType> > > Belos::PseudoBlockGmresIterState< ScalarType, MV >::Z

The current right-hand side of the least squares system RY = Z.

template<class ScalarType, class MV>
std::vector<Teuchos::RCP<const Teuchos::SerialDenseVector<int,ScalarType> > > Belos::PseudoBlockGmresIterState< ScalarType, MV >::sn

The current Given's rotation coefficients.
