class GenericLinearSolver¶

Parent class(es)

Variable

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

void set_operator(std::shared_ptr<const GenericLinearOperator> A) = 0¶: Set operator (matrix)

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

std::size_t solve_transpose(const GenericLinearOperator &A, GenericVector &x, const GenericVector &b)¶: Solve linear system A^Tx = b

std::size_t solve_transpose(GenericVector &x, const GenericVector &b)¶: Solve linear system A^Tx = b

std::string parameter_type() const¶: Return parameter type: “krylov_solver” or “lu_solver”

void update_parameters(const Parameters &parameters)¶: Update solver parameters (useful for LinearSolver wrapper)
