Detailed Description

Epetra_SerialDenseOperator: A pure virtual class for using real-valued double-precision operators.

The Epetra_SerialDenseOperator class is a pure virtual class (specifies interface only) that enable the use of real-valued double-precision operators. It is currently implemented by the Epetra_SerialDenseMatrix, Epetra_SerialDenseSolver and Epetra_SerialDenseSVD classes.

Member Function Documentation

virtual int Epetra_SerialDenseOperator::Apply ( const Epetra_SerialDenseMatrix &  X, Epetra_SerialDenseMatrix &  Y  )

pure virtual

Returns the result of a Epetra_SerialDenseOperator applied to a Epetra_SerialDenseMatrix X in Y.

Parameters

In	X - A Epetra_SerialDenseMatrix to multiply with operator.
Out	Y -A Epetra_SerialDenseMatrix containing result.

Returns

Integer error code, set to 0 if successful.

Implemented in Epetra_SerialDenseMatrix, and Epetra_SerialDenseSVD.

virtual int Epetra_SerialDenseOperator::ApplyInverse ( const Epetra_SerialDenseMatrix &  X, Epetra_SerialDenseMatrix &  Y  )

pure virtual

Returns the result of a Epetra_SerialDenseOperator inverse applied to an Epetra_SerialDenseMatrix X in Y.

Parameters

In	X - A Epetra_SerialDenseMatrix to solve for.
Out	Y -A Epetra_SerialDenseMatrix containing result.

Returns

Integer error code, set to 0 if successful.

Implemented in Epetra_SerialDenseMatrix, and Epetra_SerialDenseSVD.

virtual int Epetra_SerialDenseOperator::SetUseTranspose ( bool  UseTranspose )

pure virtual

If set true, transpose of this operator will be applied.

This flag allows the transpose of the given operator to be used implicitly.  Setting this flag
affects only the Apply() and ApplyInverse() methods.  If the implementation of this interface

does not support transpose use, this method should return a value of -1.

Parameters

In	UseTranspose -If true, multiply by the transpose of operator, otherwise just use operator.

Returns

Integer error code, set to 0 if successful. Set to -1 if this implementation does not support transpose.

Implemented in Epetra_SerialDenseMatrix, and Epetra_SerialDenseSVD.
