◆ SLESolverSP()

sgpp::solver::SLESolverSP::SLESolverSP	(	size_t	imax,
		float	epsilon
	)

inline

Std-Constructor.

Parameters

imax	number of maximum executed iterations
epsilon	the final error in the iterative solver

virtual sgpp::solver::SLESolverSP::~SLESolverSP ( )

inlinevirtual

Std-Destructor.

virtual void sgpp::solver::SLESolverSP::solve	(	sgpp::base::OperationMatrixSP &	SystemMatrix,
		sgpp::base::DataVectorSP &	alpha,
		sgpp::base::DataVectorSP &	b,
		bool	reuse = `false`,
		bool	verbose = `false`,
		float	max_threshold = `DEFAULT_RES_THRESHOLD`
	)

pure virtual

Pure virtual Function that defines a solve method for an iterative solver.

Parameters

SystemMatrix	reference to an sgpp::base::OperationMatrix Object that implements the matrix vector multiplication
alpha	the sparse grid's coefficients which have to be determined
b	the right hand side of the system of linear equations
reuse	identifies if the alphas, stored in alpha at calling time, should be reused
verbose	prints information during execution of the solver
max_threshold	additional abort criteria for solver, default value is 10^-9!
