Detailed Description

Adapter class for creating a symmetric operator from an Epetra_MultiVector.

This class will apply the operation $ A^TA$ [default] or $ AA^T$ , for the Apply method of the Epetra_Operator / Anasazi::Operator. The Anasazi::EpetraSymMvOp operator is useful when trying to compute a few singular values of the Epetra_MultiVector $ A$ . The singular values are the square-root of the eigenvalues of $ A^TA$ and $ AA^T$ .

Note: The Epetra package performs double-precision arithmetic, so the use of Epetra with Anasazi will only provide a double-precision eigensolver.

Constructor & Destructor Documentation

Anasazi::EpetraSymMVOp::EpetraSymMVOp	(	const Teuchos::RCP< const Epetra_MultiVector > &	MV,
		bool	isTrans = `false`
	)

Basic constructor for applying operator $ A^TA$ [default] or $ AA^T$ .

If isTrans is false this operator will apply $ A^TA$ , else it will apply $ AA^T$ .

Anasazi::EpetraSymMVOp::~EpetraSymMVOp ( )

inline

Destructor.

Member Function Documentation

void Anasazi::EpetraSymMVOp::Apply	(	const MultiVec< double > &	X,
		MultiVec< double > &	Y
	)		const

virtual

Apply method.

This method will apply $ A^TA$ or $ AA^T$ to X, returning Y.

Implements Anasazi::Operator< double >.
