Member Function Documentation

solve() [1/2]

virtual bool sgpp::optimization::sle_solver::SLESolver::solve ( SLE &  system, base::DataVector &  b, base::DataVector &  x  ) const

pure virtual

Pure virtual method for a solving linear system.

Parameters

	system	system to be solved
	b	right-hand side
[out]	x	solution to the system

Returns

whether all went well (false if errors occurred)

Implemented in sgpp::optimization::sle_solver::BiCGStab, sgpp::optimization::sle_solver::Auto, sgpp::optimization::sle_solver::UMFPACK, sgpp::optimization::sle_solver::Armadillo, sgpp::optimization::sle_solver::Eigen, sgpp::optimization::sle_solver::GaussianElimination, and sgpp::optimization::sle_solver::Gmmpp.

Referenced by sgpp::optimization::optimizer::LevenbergMarquardt::optimize(), sgpp::optimization::optimizer::AdaptiveNewton::optimize(), sgpp::optimization::optimizer::Newton::optimize(), solve(), and ~SLESolver().

solve() [2/2]

virtual bool sgpp::optimization::sle_solver::SLESolver::solve ( SLE &  system, base::DataMatrix &  B, base::DataMatrix &  X  ) const

inlinevirtual

Virtual method for solving multiple linear systems with different right-hand sides.

Defaults to calling the solve() method for a single right-hand side multiple times.

Parameters

	system	system to be solved
	B	matrix of right-hand sides
[out]	X	matrix of solutions to the systems

Returns

whether all went well (false if errors occurred)

Reimplemented in sgpp::optimization::sle_solver::Auto, sgpp::optimization::sle_solver::UMFPACK, sgpp::optimization::sle_solver::Armadillo, and sgpp::optimization::sle_solver::Eigen.
