Detailed Description

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

This class creates and provides basic support for banded dense matrices of templated type.

The Teuchos_SerialBandDenseMatrix class enables the construction and use of banded dense matrices of templated type.

The Teuchos::SerialBandDenseMatrix class is intended to provide full-featured support for solving
linear and eigen system problems for banded 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::SerialBandDenseMatrix vs. Teuchos::LAPACK</b>

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

Constructing Teuchos::SerialBandDenseMatrix Objects

There are three Teuchos::SerialBandDenseMatrix 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):

  1. Copy mode - Allocates memory and makes a copy of the user-provided data. In this case, the user data is not needed after construction.
  2. 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.

Format of the matrix A

The matrix A is stored as a banded matrix AB according to the LAPACK format. Consider using the non-member conversion routines generalToBanded and bandedToGeneral if the full Teuchos::SerialDenseMatrix is already in storage. However, it is more efficient to simply construct the Teuchos::SerialBandDenseMatrix with the desired parameters and use the provided matrix access operators to assign (legal) entries so that the full rectangular matrix does not need to be stored. A full description of the LAPACK banded format can be found at http://www.netlib.org/lapack/lug/node124.html. Briefly, the banded storage format of AB used internally is as follows:

Extracting Data from Teuchos::SerialBandDenseMatrix Objects

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

Constructor & Destructor Documentation

template<typename OrdinalType , typename ScalarType >
Teuchos::SerialBandDenseMatrix< OrdinalType, ScalarType >::SerialBandDenseMatrix ( )

Default Constructor.

Creates a empty matrix of no dimension. The Shaping methods should be used to size this matrix. Values of this matrix should be set using the [], (), or = operators.

Definition at line 451 of file Teuchos_SerialBandDenseMatrix.hpp.

template<typename OrdinalType , typename ScalarType >
Teuchos::SerialBandDenseMatrix< OrdinalType, ScalarType >::SerialBandDenseMatrix ( OrdinalType  numRows,
OrdinalType  numCols,
OrdinalType  kl,
OrdinalType  ku,
bool  zeroOut = true 
)

Shaped Constructor.

Parameters
numRows- Number of rows in matrix.
numCols- Number of columns in matrix.
kl- Lower bandwidth of matrix.
ku- Upper bandwidth of matrix.
zeroOut- Initializes values to 0 if true (default)

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

Definition at line 465 of file Teuchos_SerialBandDenseMatrix.hpp.

template<typename OrdinalType , typename ScalarType >
Teuchos::SerialBandDenseMatrix< OrdinalType, ScalarType >::SerialBandDenseMatrix ( DataAccess  CV,
ScalarType *  values,
OrdinalType  stride,
OrdinalType  numRows,
OrdinalType  numCols,
OrdinalType  kl,
OrdinalType  ku 
)

Shaped Constructor with Values.

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.
numRows- Number of rows in matrix.
numCols- Number of columns in matrix.
kl- Lower bandwidth of matrix.
ku- Upper bandwidth of matrix.

Definition at line 488 of file Teuchos_SerialBandDenseMatrix.hpp.

template<typename OrdinalType , typename ScalarType >
Teuchos::SerialBandDenseMatrix< OrdinalType, ScalarType >::SerialBandDenseMatrix ( const SerialBandDenseMatrix< OrdinalType, ScalarType > &  Source,
ETransp  trans = Teuchos::NO_TRANS 
)

Copy Constructor.

Note
A deep copy of the Source transposed can be obtained if trans=Teuchos::TRANS, else a non-transposed copy of Source is made. There is no storage of the transpose state of the matrix within the SerialBandDenseMatrix class, so this information will not propogate to any operation performed on a matrix that has been copy constructed in transpose.

template<typename OrdinalType , typename ScalarType >
Teuchos::SerialBandDenseMatrix< OrdinalType, ScalarType >::SerialBandDenseMatrix ( DataAccess  CV,
const SerialBandDenseMatrix< OrdinalType, ScalarType > &  Source,
OrdinalType  numRows,
OrdinalType  numCols,
OrdinalType  startCol = 0 
)

Submatrix Copy Constructor.

Parameters
CV- Enumerated type set to Teuchos::Copy or Teuchos::View.
Source- Reference to another dense matrix from which values are to be copied.
numRows- The number of rows in this matrix.
numCols- The number of columns in this matrix.
kl- Lower bandwidth of matrix.
ku- Upper bandwidth of matrix.
startRow- The row of Source from which the submatrix copy should start.
startCol- The column of Source from which the submatrix copy should start.

Creates a shaped matrix with numRows rows and numCols columns, which is a submatrix of Source. If startRow and startCol are not given, then the submatrix is the leading submatrix of Source. Otherwise, the (1,1) entry in the copied matrix is the (startRow, startCol) entry of Source.

A templated, non-member, helper function for converting a SerialBandDenseMatrix to a SerialDenseMatrix.

Parameters
A- [in] SerialBandDenseMatrix to be converted
Note
The syntax for calling this function is: Teuchos::SerialDenseMatrix<int,double> A = Teuchos::bandedToGeneral<int,double>( AB )
