Epetra_SerialDenseVector: A class for constructing and using dense vectors. The Epetra_SerialDenseVector class enables the construction and use of real-valued, double- precision dense vectors. It is built on the BLAS and LAPACK and derives from the Epetra_SerialDenseMatrix class. The Epetra_SerialDenseVector class is intended to provide convenient vector notation but derives all signficant functionality from Epetra_SerialDenseMatrix. Constructing Epetra_SerialDenseVector Objects There are four Epetra_SerialDenseVector constructors. The first constructs a zero-length object which should be made to appropriate length using the Size() or Resize() functions and then filled with the [] or () operators. The second constructs an object sized to the dimension specified, which should be filled with the [] or () operators. The third is a constructor that accepts user data as a 1D array, and the fourth is a copy constructor. The third constructor has two data access modes (specified by the Epetra_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 Epetra_SerialDenseVector Objects Once a Epetra_SerialDenseVector 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. The final useful function is Flops(). Each Epetra_SerialDenseVector object keep track of the number of serial floating point operations performed using the specified object as the this argument to the function. The Flops() function returns this number as a double precision number. Using this information, in conjunction with the Epetra_Time class, one can get accurate parallel performance numbers.
