Member Data Documentation

curDim

template<class ScalarType , class MV , class DM >

int Belos::PseudoBlockGmresIterState< ScalarType, MV, DM >::curDim

The current dimension of the reduction.

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

Definition at line 82 of file BelosGmresIteration.hpp.

V

template<class ScalarType , class MV , class DM >

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

The current Krylov basis.

Definition at line 84 of file BelosGmresIteration.hpp.

H

template<class ScalarType , class MV , class DM >

std::vector<Teuchos::RCP<const DM> > Belos::PseudoBlockGmresIterState< ScalarType, MV, DM >::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 90 of file BelosGmresIteration.hpp.

R

template<class ScalarType , class MV , class DM >

std::vector<Teuchos::RCP<const DM> > Belos::PseudoBlockGmresIterState< ScalarType, MV, DM >::R

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

Definition at line 92 of file BelosGmresIteration.hpp.

Z

template<class ScalarType , class MV , class DM >

std::vector<Teuchos::RCP<const DM> > Belos::PseudoBlockGmresIterState< ScalarType, MV, DM >::Z

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

Definition at line 94 of file BelosGmresIteration.hpp.

sn

template<class ScalarType , class MV , class DM >

std::vector<Teuchos::RCP<const std::vector<ScalarType> > > Belos::PseudoBlockGmresIterState< ScalarType, MV, DM >::sn

The current Given's rotation coefficients.

Definition at line 96 of file BelosGmresIteration.hpp.
