Detailed Description

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

This class creates and provides basic support for symmetric, positive-definite dense matrices of templated type.

The Teuchos_SerialSymDenseMatrix class enables the construction and use of
symmetric, positive-definite, dense matrices of templated type.

The Teuchos::SerialSymDenseMatrix class is intended to provide full-featured support for solving
linear and eigen system problems for symmetric positive-definite (SPD) 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.

<b>Teuchos::SerialSymDenseMatrix vs. Teuchos::LAPACK</b>

The Teuchos::LAPACK class provides access to most of the same functionality as Teuchos::SerialSymDenseMatrix.
The primary difference is that Teuchos::LAPACK is a "thin" layer on top of LAPACK and
Teuchos::SerialSymDenseMatrix 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::SerialSymDenseMatrix: 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::SerialSymDenseMatrix.

Constructing Teuchos::SerialSymDenseMatrix Objects

There are three Teuchos::SerialSymDenseMatrix constructors. The first constructs a zero-sized object which should be made to appropriate length using the Shape() or Reshape() functions and then filled with the [] or () operators. The second is a constructor that accepts user data as a 2D array, the third is a copy constructor. The second constructor has two data access modes (specified by the Teuchos::DataAccess argument):

Copy mode - Allocates memory and makes a copy of the user-provided data. In this case, the user data is not needed after construction.
View mode - Creates a "view" of the user data. In this case, the user data is required to remain intact for the life of the object.

Warning: View mode is extremely dangerous from a data hiding perspective. Therefore, we strongly encourage users to develop code using Copy mode first and only use the View mode in a secondary optimization phase.

Extracting Data from Teuchos::SerialSymDenseMatrix Objects

Once a Teuchos::SerialSymDenseMatrix is constructed, it is possible to view the data via access functions.

Warning: Use of these access functions cam be extremely dangerous from a data hiding perspective.

Vector and Utility Functions

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

Multiplication.
Norms.

Constructor & Destructor Documentation

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialSymDenseMatrix< OrdinalType, ScalarType >::SerialSymDenseMatrix ( )

Default constructor; defines a zero size object.

Teuchos::SerialSymDenseMatrix objects defined by the default constructor should be sized with the Shape() or Reshape() functions. Values should be defined by using the [] or ()operators.

Note: By default the active part of the matrix is assumed to be the lower triangular part. To set the upper part as active, call SetUpper(). See Detailed Description section for further discussion.

Definition at line 441 of file Teuchos_SerialSymDenseMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialSymDenseMatrix< OrdinalType, ScalarType >::SerialSymDenseMatrix	(	OrdinalType	numRowsCols,
		bool	zeroOut = `true`
	)

Basic constructor; defines a matrix of numRowsCols size and (optionally) initializes it.

Parameters

numRowsCols	- Number of rows and columns in the matrix.
zeroOut	- Initializes values to 0 if true (default)

Creates a shaped matrix with numRowsCols rows and cols. All values are initialized to 0 when zeroOut is true. Values of this matrix should be set using the [] or the () operators.

Note: By default the active part of the matrix is assumed to be the lower triangular part. To set the upper part as active, call SetUpper(). See Detailed Description section for further discussion.

		OrdinalType	numRowsCols
	)

Set object values from two-dimensional array.

Parameters

CV	- Enumerated type set to Teuchos::Copy or Teuchos::View.
values	- Pointer to an array of ScalarType. The first column starts at `values`, the second at `values+stride`, etc.
stride	- The stride between the columns of the matrix in memory.
numRowsCols	- Number of rows and columns in the matrix.

Note: By default the active part of the matrix is assumed to be the lower triangular part. To set the upper part as active, call SetUpper(). See Detailed Description section for further discussion.

int Teuchos::SerialSymDenseMatrix< OrdinalType, ScalarType >::shape ( OrdinalType numRowsCols )

Set dimensions of a Teuchos::SerialSymDenseMatrix object; init values to zero.

Parameters

numRowsCols - Number of rows and columns in object.

Allows user to define the dimensions of a Teuchos::SerialSymDenseMatrix at any point. This function can be called at any point after construction. Any values that were previously in this object are destroyed and the resized matrix starts off with all zero values.

Returns: Integer error code, set to 0 if successful.

template<typename OrdinalType , typename ScalarType >

int Teuchos::SerialSymDenseMatrix< OrdinalType, ScalarType >::shapeUninitialized ( OrdinalType numRowsCols )

Set dimensions of a Teuchos::SerialSymDenseMatrix object; don't initialize values.

Parameters

numRowsCols - Number of rows and columns in object.

Allows user to define the dimensions of a Teuchos::SerialSymDenseMatrix at any point. This function can be called at any point after construction. Any values that were previously in this object are destroyed. The resized matrix has uninitialized values.

Returns: Integer error code, set to 0 if successful.

Definition at line 549 of file Teuchos_SerialSymDenseMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

int Teuchos::SerialSymDenseMatrix< OrdinalType, ScalarType >::reshape ( OrdinalType numRowsCols )

Reshape a Teuchos::SerialSymDenseMatrix object.

Parameters

numRowsCols - Number of rows and columns in object.

Allows user to define the dimensions of a Teuchos::SerialSymDenseMatrix at any point. This function can be called at any point after construction. Any values that were previously in this object are copied into the new shape. If the new shape is smaller than the original, the upper left portion of the original matrix (the principal submatrix) is copied to the new matrix.

Returns: Integer error code, set to 0 if successful.
