Constructors/Destructor

 Iteration ()
 Default Constructor.
 Iteration (const Teuchos::RCP< LinearProblem< ScalarType, MV, OP > > &problem, const Teuchos::RCP< OutputManager< ScalarType > > &printer, const Teuchos::RCP< StatusTest< ScalarType, MV, OP > > &tester, const Teuchos::RCP< MatOrthoManager< ScalarType, MV, OP > > &ortho, Teuchos::ParameterList &params)
 Basic Constructor.
virtual ~Iteration ()
 Destructor.
Solver methods

virtual void iterate ()=0
 This method performs linear solver iterations until the status test indicates the need to stop or an error occurs (in which case, an std::exception is thrown).
virtual void initialize ()=0
 Initialize the solver with the initial vectors from the linear problem or random data.
Status methods

virtual int getNumIters () const =0
 Get the current iteration count.
virtual void resetNumIters (int iter=0)=0
 Reset the iteration count to iter.
virtual Teuchos::RCP< const MV > getNativeResiduals (std::vector< typename Teuchos::ScalarTraits< ScalarType >::magnitudeType > *norms) const =0
 Get the residuals native to the solver.
virtual Teuchos::RCP< MV > getCurrentUpdate () const =0
 Get the current update to the linear system.
Accessor methods

virtual const LinearProblem
< ScalarType, MV, OP > & 
getProblem () const =0
 Get a constant reference to the linear problem.
virtual int getBlockSize () const =0
 Get the blocksize to be used by the iterative solver in solving this linear problem.
virtual void setBlockSize (int blockSize)=0
 Set the blocksize to be used by the iterative solver in solving this linear problem.
virtual bool isInitialized ()=0
 States whether the solver has been initialized or not.

template<class ScalarType, class MV, class OP>
Belos::Iteration< ScalarType, MV, OP >::Iteration (  )  [inline]

Default Constructor.

Definition at line 66 of file BelosIteration.hpp.

template<class ScalarType, class MV, class OP>
Belos::Iteration< ScalarType, MV, OP >::Iteration ( const Teuchos::RCP< LinearProblem< ScalarType, MV, OP > > &  problem,
const Teuchos::RCP< OutputManager< ScalarType > > &  printer,
const Teuchos::RCP< StatusTest< ScalarType, MV, OP > > &  tester,
const Teuchos::RCP< MatOrthoManager< ScalarType, MV, OP > > &  ortho,
Teuchos::ParameterList params 
)

Basic Constructor.

This constructor, implemented by all Belos iterations, takes an Belos::LinearProblem, Belos::OrthoManager, Belos::OutputManager, and Teuchos::ParameterList as input. These four arguments are sufficient enough for constructing any Belos::Iteration object.

Get the residuals native to the solver.

Returns:
A multivector with blockSize vectors containing the native residuals, else the native residual norm is returned.
