Constructor & Destructor Documentation

template<typename OrdinalType , typename ScalarType >

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

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 363 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::SerialTriDiMatrix	(	OrdinalType	numRows,
		OrdinalType	numCols,
		bool	zeroOut = `true`
	)

Shaped Constructor.

Parameters

numRows	- Number of rows in matrix.
numCols	- Number of columns in 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 376 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::SerialTriDiMatrix	(	DataAccess	CV,
		ScalarType *	values,
		OrdinalType	numRowsCols
	)

Shaped Constructor with Values.

Parameters

CV	- Enumerated type set to Teuchos::Copy or Teuchos::View.
values	- Pointer to an array of ScalarType.
numRowsCols	- Number of rows and columns in matrix.

Definition at line 392 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::SerialTriDiMatrix	(	const SerialTriDiMatrix< 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 SerialTriDiMatrix class, so this information will not propogate to any operation performed on a matrix that has been copy constructed in transpose.

Definition at line 417 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::SerialTriDiMatrix	(	DataAccess	CV,
		const SerialTriDiMatrix< OrdinalType, ScalarType > &	Source,
		OrdinalType	numRowsCols,
		OrdinalType	startRowCols = `0`
	)

Submatrix Copy Constructor.

Parameters

CV	- Enumerated type set to Teuchos::Copy or Teuchos::View.
Source	- Reference to another TriDi matrix from which values are to be copied.
numRowsCols	- The number of rows and columns in this matrix.
startRowCols	- The row and col of `Source` from which the submatrix copy should start.

Creates a shaped matrix with numRowsCols rows and columns, which is a submatrix of Source. If startRowCols, 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.

Member Function Documentation

template<typename OrdinalType , typename ScalarType >

int Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::shape ( OrdinalType numRows )

Shape method for changing the size of a SerialTriDiMatrix, initializing entries to zero.

Parameters

numRowsCols - The number of rows in this matrix.

This method allows the user to define the dimensions of a SerialTriDiMatrix at any point. This method can be called at any point after construction. Any values previously in this object will be destroyed and the resized matrix starts of with all zero values.

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

Definition at line 506 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

int Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::shapeUninitialized ( OrdinalType numRows )

Definition at line 519 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

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

Reshaping method for changing the size of a SerialTriDiMatrix, keeping the entries.

Parameters

numRowsCols - The number of rows in this matrix.

This method allows the user to redefine the dimensions of a SerialTriDiMatrix at any point. This method can be called at any point after construction. Any values previously in this object will be copied into the reshaped matrix.

Returns: Integer error code, set 0 if successful.

Definition at line 530 of file Teuchos_SerialTriDiMatrix.hpp.

template<typename OrdinalType , typename ScalarType >

SerialTriDiMatrix< OrdinalType, ScalarType > & Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::operator= ( const SerialTriDiMatrix< OrdinalType, ScalarType > & Source )

Copies values from one matrix to another.

The operator= copies the values from one existing SerialTriDiMatrix to another. If Source is a view (i.e. CV = Teuchos::View), then this method will return a view. Otherwise, it will return a copy of Source. this object will be resized if it is not large enough to copy Source into.

template<typename OrdinalType , typename ScalarType >

SerialTriDiMatrix< OrdinalType, ScalarType > & Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::assign ( const SerialTriDiMatrix< OrdinalType, ScalarType > & Source )

Returns: True if this matrix and Operand are of the same shape (rows and columns) and have the same entries, else False will be returned.

bool Teuchos::SerialTriDiMatrix< OrdinalType, ScalarType >::operator!= ( const SerialTriDiMatrix< OrdinalType, ScalarType > & Operand ) const

Inequality of two matrices.

Returns: True if this matrix and Operand of not of the same shape (rows and columns) or don't have the same entries, else False will be returned.
