	AnasaziMV (int dim=0, int nvecs=0, bool allocate=true)
virtual AnasaziMV< ScalarT > *	Clone (const int numvecs) const
	Creates a new empty Anasazi::MultiVec containing numvecs columns.
virtual AnasaziMV< ScalarT > *	CloneCopy () const
	Creates a new Anasazi::MultiVec and copies contents of *this into the new vector (deep copy).
virtual AnasaziMV< ScalarT > *	CloneCopy (const std::vector< int > &index) const
	Creates a new Anasazi::MultiVec and copies the selected contents of *this into the new vector (deep copy). The copied vectors from *this are indicated by the index.size() indices in index.
virtual AnasaziMV< ScalarT > *	CloneView (const std::vector< int > &index)
	Creates a new Anasazi::MultiVec that shares the selected contents of *this. The index of the numvecs vectors shallow copied from *this are indicated by the indices given in index.
Attribute methods
int	GetVecLength () const
	Obtain the vector length of *this.
virtual int	GetNumberVecs () const
	Obtain the number of vectors in *this.
Update methods
virtual void	MvTimesMatAddMv (ScalarT alpha, const Anasazi::MultiVec< ScalarT > &A, const Teuchos::SerialDenseMatrix< int, ScalarT > &B, ScalarT beta)
	Update *this with alpha * A * B + beta * (*this).
virtual void	MvAddMv (ScalarT alpha, const Anasazi::MultiVec< ScalarT > &A, ScalarT beta, const Anasazi::MultiVec< ScalarT > &B)
