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.
