Constructor/Destructor  
Operator ()  
Default constructor.  
virtual  ~Operator () 
Destructor.  
Operator application method  
virtual void  Apply (const MultiVec< ScalarType > &x, MultiVec< ScalarType > &y, ETrans trans=NOTRANS) const =0 
This routine takes the Belos::MultiVec x and applies the operator to it resulting in the Belos::MultiVec y , which is returned. 
Belos's templated pure virtual class for constructing the operator that is used by the linear solver.
This operator is used as the interface to the matrix (A
), solution (X
), and righthand side (B
) of the linear system AX = B
. Furthermore, it is also the interface to left/right preconditioning and left/right scaling of the linear system.
A concrete implementation of this class is necessary. The user can create their own implementation if those supplied are not suitable for their needs.

This routine takes the Belos::MultiVec x
and applies the operator to it resulting in the Belos::MultiVec y
, which is returned.
x
will be indicated by an std::exception being thrown. Implemented in MyBetterOperator< ScalarType >, and MyOperator< ScalarType >.
