Detailed Description

Epetra_SerialDenseSVD: A class for SVDing dense linear problems.

The Epetra_SerialDenseSVD class enables the definition, in terms of Epetra_SerialDenseMatrix
and Epetra_SerialDenseVector objects, of a dense linear problem, followed by the solution of that problem via the
most sophisticated techniques available in LAPACK.

The Epetra_SerialDenseSVD 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.

Epetra_SerialDenseSVD vs. Epetra_LAPACK

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

Constructing Epetra_SerialDenseSVD Objects

There is a single Epetra_SerialDenseSVD 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 Epetra_SerialDenseMatrix or and Epetra_SerialDenseVector object. The set methods are as follows:

Vector and Utility Functions

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

Counting floating point operations The Epetra_SerialDenseSVD class has Epetra_CompObject as a base class. Thus, floating point operations are counted and accumulated in the Epetra_Flop object (if any) that was set using the SetFlopCounter() method in the Epetra_CompObject base class.

Examples using Epetra_SerialDenseSVD can be found in the Epetra test directories.
