Creation methods
Teuchos::RefCountPtr< Epetra_MultiVector > Clone (const Epetra_MultiVector &mv, const int numvecs)
 Creates a new empty Epetra_MultiVector containing numvecs columns.
Teuchos::RefCountPtr< Epetra_MultiVector > CloneCopy (const Epetra_MultiVector &mv)
 Creates a new Epetra_MultiVector and copies contents of mv into the new vector (deep copy).
Teuchos::RefCountPtr< Epetra_MultiVector > CloneCopy (const Epetra_MultiVector &mv, const std::vector< int > &index)
 Creates a new Epetra_MultiVector and copies the selected contents of mv into the new vector (deep copy).
Teuchos::RefCountPtr< Epetra_MultiVector > CloneView (Epetra_MultiVector &mv, const std::vector< int > &index)
 Creates a new Epetra_MultiVector that shares the selected contents of mv (shallow copy).
Teuchos::RefCountPtr< const
Epetra_MultiVector > 		CloneView (const Epetra_MultiVector &mv, const std::vector< int > &index)
 Creates a new const Epetra_MultiVector that shares the selected contents of mv (shallow copy).
Attribute methods
int GetVecLength (const Epetra_MultiVector &mv)
 Obtain the vector length of mv.
int GetNumberVecs (const Epetra_MultiVector &mv)
 Obtain the number of vectors in mv.
Update methods
void MvTimesMatAddMv (const double alpha, const Epetra_MultiVector &A, const Teuchos::SerialDenseMatrix< int, double > &B, const double beta, Epetra_MultiVector &mv)
 Update mv with $ \alpha AB + \beta mv $.
void MvAddMv (const double alpha, const Epetra_MultiVector &A, const double beta, const Epetra_MultiVector &B, Epetra_MultiVector &mv)
 Replace mv with $\alpha A + \beta B$.
void MvTransMv (const double alpha, const Epetra_MultiVector &A, const Epetra_MultiVector &mv, Teuchos::SerialDenseMatrix< int, double > &B)
 Compute a dense matrix B through the matrix-matrix multiply $ \alpha A^Tmv $.
void MvDot (const Epetra_MultiVector &mv, const Epetra_MultiVector &A, std::vector< double > *b)

Detailed Description

template<>
class Anasazi::MultiVecTraits< double, Epetra_MultiVector >

Template specialization of Anasazi::MultiVecTraits class using the Epetra_MultiVector class.

This interface will ensure that any Epetra_MultiVector will be accepted by the Anasazi templated solvers.

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