Collection of types and exceptions used within the Belos solvers.
Pure virtual base class which describes the basic interface to the linear solver iteration.
virtual FixedPointIterationState< ScalarType, MV > getState() const =0
Get the current state of the linear solver.
Teuchos::RCP< const MV > R
The current residual.
virtual void initializeFixedPoint(FixedPointIterationState< ScalarType, MV > &newstate)=0
Initialize the solver to an iterate, providing a complete state.
Structure to contain pointers to FixedPointIteration state variables.
Teuchos::RCP< const MV > Z
The current preconditioned residual.
Belos header file which uses auto-configuration information to include necessary C++ headers...
