Detailed Description

template<typename OrdinalType, typename ScalarType>
class Teuchos::SerialDenseSolver< OrdinalType, ScalarType >

A class for solving dense linear problems.

The Teuchos::SerialDenseSolver class enables the definition, in terms of Teuchos::SerialDenseMatrix and Teuchos::SerialDenseVector objects, of a dense linear problem, followed by the solution of that problem via the most sophisticated techniques available in LAPACK.

The Teuchos::SerialDenseSolver class is intended to provide full-featured support for solving linear problems for general dense rectangular (or square) matrices. It is written on top of BLAS and LAPACK and thus has excellent performance and numerical capabilities. Using this class, one can either perform simple factorizations and solves or apply all the tricks available in LAPACK to get the best possible solution for very ill-conditioned problems.

Teuchos::SerialDenseSolver vs. Teuchos::LAPACK

The Teuchos::LAPACK class provides access to most of the same functionality as Teuchos::SerialDenseSolver. The primary difference is that Teuchos::LAPACK is a "thin" layer on top of LAPACK and Teuchos::SerialDenseSolver attempts to provide easy access to the more sophisticated aspects of solving dense linear and eigensystems.

When you should use Teuchos::LAPACK: If you are simply looking for a convenient wrapper around the Fortran LAPACK routines and you have a well-conditioned problem, you should probably use Teuchos::LAPACK directly.
When you should use Teuchos::SerialDenseSolver: If you want to (or potentially want to) solve ill-conditioned problems or want to work with a more object-oriented interface, you should probably use Teuchos::SerialDenseSolver.

Constructing Teuchos::SerialDenseSolver Objects

There is a single Teuchos::SerialDenseSolver constructor. However, the matrix, right hand side and solution vectors must be set prior to executing most methods in this class.

Setting vectors used for linear solves

The matrix A, the left hand side X and the right hand side B (when solving AX = B, for X), can be set by appropriate set methods. Each of these three objects must be an Teuchos::SerialDenseMatrix or and Teuchos::SerialDenseVector object. The set methods are as follows:

setMatrix() - Sets the matrix.
setVectors() - Sets the left and right hand side vector(s).

Vector and Utility Functions

Once a Teuchos::SerialDenseSolver is constructed, several mathematical functions can be applied to the object. Specifically:

Factorizations.
Solves.
Condition estimates.
Equilibration.
Norms.

Strategies for Solving Linear Systems In many cases, linear systems can be accurately solved by simply computing the LU factorization of the matrix and then performing a forward back solve with a given set of right hand side vectors. However, in some instances, the factorization may be very poorly conditioned and this simple approach may not work. In these situations, equilibration and iterative refinement may improve the accuracy, or prevent a breakdown in the factorization.

Teuchos::SerialDenseSolver will use equilibration with the factorization if, once the object is constructed and before it is factored, you call the function factorWithEquilibration(true) to force equilibration to be used. If you are uncertain if equilibration should be used, you may call the function shouldEquilibrate() which will return true if equilibration could possibly help. shouldEquilibrate() uses guidelines specified in the LAPACK User Guide, namely if SCOND < 0.1 and AMAX < Underflow or AMAX > Overflow, to determine if equilibration might be useful.

Teuchos::SerialDenseSolver will use iterative refinement after a forward/back solve if you call solveToRefinedSolution(true). It will also compute forward and backward error estimates if you call estimateSolutionErrors(true). Access to the forward (back) error estimates is available via FERR() (BERR()).

Examples using Teuchos::SerialDenseSolver can be found in the Teuchos test directories.
