class EpetraLUSolver¶

Parent class(es)

GenericLUSolver

This class implements the direct solution (LU factorization) for linear systems of the form Ax = b. It is a wrapper for the LU solver of Epetra.

EpetraLUSolver(std::string method = "default")¶: Constructor

EpetraLUSolver(std::shared_ptr<const GenericLinearOperator> A, std::string method = "default")¶: Constructor

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

const GenericLinearOperator &get_operator() const¶: Get operator (matrix)

std::size_t solve(GenericVector &x, const GenericVector &b)¶: Solve linear system Ax = b

std::size_t solve(const GenericLinearOperator &A, GenericVector &x, const GenericVector &b)¶: Solve linear system Ax = b

std::size_t solve(const EpetraMatrix &A, EpetraVector &x, const EpetraVector &b)¶: Solve linear system Ax = b

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

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