class EpetraKrylovSolver

Parent class(es)

This class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of Epetra.

EpetraKrylovSolver(std::string method = "default", std::string preconditioner = "default")

Create Krylov solver for a particular method and preconditioner

EpetraKrylovSolver(std::string method, TrilinosPreconditioner &preconditioner)

Create Krylov solver for a particular method and TrilinosPreconditioner

void set_operator(const boost::shared_ptr<const GenericLinearOperator> A)

Set the operator (matrix)

void set_operators(const boost::shared_ptr<const GenericLinearOperator> A, const boost::shared_ptr<const GenericLinearOperator> P)

Set the operator (matrix)

const GenericLinearOperator &get_operator() const

Get the operator (matrix)

std::size_t solve(GenericVector &x, const GenericVector &b)
