Member Function Documentation

solve() [1/2]

virtual bool sgpp::base::sle_solver::SLESolver::solve ( SLE &  system, DataMatrix &  B, 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::base::sle_solver::Armadillo, sgpp::base::sle_solver::Auto, sgpp::base::sle_solver::Eigen, and sgpp::base::sle_solver::UMFPACK.

solve() [2/2]

virtual bool sgpp::base::sle_solver::SLESolver::solve ( SLE &  system, DataVector &  b, 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::base::sle_solver::Armadillo, sgpp::base::sle_solver::Auto, sgpp::base::sle_solver::BiCGStab, sgpp::base::sle_solver::Eigen, sgpp::base::sle_solver::GaussianElimination, sgpp::base::sle_solver::Gmmpp, and sgpp::base::sle_solver::UMFPACK.
