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.
Parent class to all Belos exceptions.
MinresIterateFailure is thrown when the MinresIteration object is unable to compute the next iterate ...
MinresIterateFailure(const std::string &what_arg)
virtual MinresIterationState< ScalarType, MV > getState() const =0
Get the current state of the linear solver.
virtual void initializeMinres(const MinresIterationState< ScalarType, MV > &newstate)=0
Initialize the solver to an iterate, providing a complete state.
Structure to contain pointers to MinresIteration state variables.
