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.
