class EigenKrylovSolver

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 Eigen.

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

Create Krylov solver for a particular method and names preconditioner

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

Set operator (matrix)

void set_operator(std::shared_ptr<const EigenMatrix> A)

Set operator (matrix)

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

Set operator (matrix) and preconditioner matrix

void set_operators(std::shared_ptr<const EigenMatrix> A, std::shared_ptr<const EigenMatrix> P)

Set operator (matrix) and preconditioner matrix

const EigenMatrix &get_operator() const

Get operator (matrix)

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

Solve linear system Ax = b and return number of iterations

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

Solve linear system Ax = b and return number of iterations

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