Static Public Member Functions
Creation methods
static Teuchos::RCP< MV >	Clone (const MV &mv, const int numvecs)
	Creates a new empty `MV` containing `numvecs` columns.
static Teuchos::RCP< MV >	CloneCopy (const MV &mv)
	Creates a new `MV` and copies contents of `mv` into the new vector (deep copy).
static Teuchos::RCP< MV >	CloneCopy (const MV &mv, const std::vector< int > &index)
	Creates a new `MV` and copies the selected contents of `mv` into the new vector (deep copy).
static Teuchos::RCP< MV >	CloneViewNonConst (MV &mv, const std::vector< int > &index)
	Creates a new `MV` that shares the selected contents of `mv` (shallow copy).
static Teuchos::RCP< const MV >	CloneView (const MV &mv, const std::vector< int > &index)
	Creates a new const `MV` that shares the selected contents of `mv` (shallow copy).
Attribute methods
static int	GetVecLength (const MV &mv)
	Obtain the vector length of `mv`.

Detailed Description

template<class ScalarType, class MV>
class Anasazi::MultiVecTraits< ScalarType, MV >

Virtual base class which defines basic traits for the multi-vector type.

An adapter for this traits class must exist for the MV type. If not, this class will produce a compile-time error.
