Detailed Description

template<class ScalarType>
class Belos::Operator< ScalarType >

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 right-hand 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.

Member Function Documentation

template<class ScalarType>

virtual void Belos::Operator< ScalarType >::Apply	(	const MultiVec< ScalarType > &	x,
		MultiVec< ScalarType > &	y,
		ETrans	trans = NOTRANS
	)			const [pure virtual]

This routine takes the Belos::MultiVec x and applies the operator to it resulting in the Belos::MultiVec y, which is returned.

Note:

It is expected that any problem with applying this operator to x will be indicated by an std::exception being thrown.

Implemented in Belos::EpetraOp, and Belos::EpetraPrecOp.
