Constructor & Destructor Documentation

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

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 the () operators. Definition at line 322 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::SerialDenseMatrix (  int  numRows, int  numCols )

Shaped Constructor. Parameters: numRows  - Number of rows in matrix. numCols  - Number of columns in matrix. Creates a shaped matrix with numRows rows and numCols cols. All values are initialized to 0. Values of this matrix should be set using the [] or the () operators. Definition at line 325 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::SerialDenseMatrix (  DataAccess  CV, ScalarType *  values, int  stride, int  numRows, int  numCols )

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. Definition at line 333 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::SerialDenseMatrix (  const SerialDenseMatrix< OrdinalType, ScalarType > &  Source  )

Copy Constructor. Definition at line 345 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::SerialDenseMatrix (  DataAccess  CV, const SerialDenseMatrix< OrdinalType, ScalarType > &  Source, int  numRows, int  numCols, int  startRow = 0, int  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. 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. Definition at line 353 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> int Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::shape (  int  numRows, int  numCols )

Shape method for changing the size of a SerialDenseMatrix, initializing entries to zero. Parameters: numRows  - The number of rows in this matrix. numCols  - The number of columns in this matrix. This method allows the user to define the dimensions of a SerialDenseMatrix 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 379 of file Teuchos_SerialDenseMatrix.hpp.

template<typename OrdinalType, typename ScalarType> int Teuchos::SerialDenseMatrix< OrdinalType, ScalarType >::reshape (  int  numRows, int  numCols )

Reshaping method for changing the size of a SerialDenseMatrix, keeping the entries. Parameters: numRows  - The number of rows in this matrix. numCols  - The number of columns in this matrix. This method allows the user to redefine the dimensions of a SerialDenseMatrix at any point. This method can be called at any point after construction.
