Detailed Description

Epetra_SLU: An object-oriented wrapper for Xiaoye Li's serial sparse solver package: Superlu.

Epetra_SLU will solve a linear systems of equations: , using Epetra objects and the Superludist solver library, where is an Epetra_RowMatrix and and are Epetra_MultiVector objects.

SuperLU execution can be tuned through a variety of parameters. Three parameters can be controlled within the call to the constructor: fill_fac, panel_size and relax. Seven parameters can be controlled within the call to Solve(): Verbose, Equil, Factor, perm_type, pivot_thresh, Refact, Trans

Constructor & Destructor Documentation

Epetra_SLU::Epetra_SLU	(	Epetra_LinearProblem *	Problem,
		int	fill_fac = -1,
		int	panel_size = -1,
		int	relax = -1
	)

Epetra_SLU Constructor.

Creates an Epetra_SLU instance, using an Epetra_LinearProblem, passing in an already-defined Epetra_LinearProblem object.

Epetra_SLU::~Epetra_SLU

(

)

Epetra_SLU Destructor.

Completely deletes a Epetra_SLU object.

Member Function Documentation

int Epetra_SLU::Solve	(	bool	Verbose = false,
		bool	Equil = true,
		bool	Factor = true,
		int	perm_type = 2,
		double	pivot_thresh = -1,
		bool	Refact = true,
		bool	Trans = false
	)

All computation is performed during the call to Solve()

Factor controls whether or not the matrix should be factored prior to the solve. Default is true.
