class LinearSolver

Parent class(es)

• GenericLinearSolver

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(std::shared_ptr<const GenericLinearOperator> A)

Set the operator (matrix)

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

Set the operator (matrix) and preconditioner 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

void update_parameters(const Parameters& parameters)

Update solver parameters (pass parameters down to wrapped implementation)

std::string parameter_type() const

Return parameter type: “krylov_solver” or “lu_solver”
