class LinearSolver

Parent class(es)

This class provides a general solver for linear systems Ax = b.

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

Create linear solver

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) and preconitioner matrix

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

Solve linear system Ax = b

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

Solve linear system Ax = b

static Parameters default_parameters()

Default parameter values

std::string parameter_type() const

Return parameter type: “krylov_solver” or “lu_solver”

void update_parameters(const Parameters &parameters)
