Detailed Description

Adapter class for creating a symmetric operator from an Epetra_MultiVector.

This class will apply the operation [default] or , 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 . The singular values are the square-root of the eigenvalues of and .

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

◆ EpetraSymMVOp()

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

Basic constructor for applying operator [default] or .

If isTrans is false this operator will apply , else it will apply .
