Belos header file which uses auto-configuration information to include necessary C++ headers.
Pure virtual base class which describes the basic interface to the linear solver iteration.
Collection of types and exceptions used within the Belos solvers.
virtual StochasticCGIterationState< ScalarType, MV > getState() const =0
