Detailed Description

template<class Scalar>
class Playa::InverseOperator< Scalar >

PlayaInverseOperator represents the inverse of some other operator. An inverse operator object will contain an operator and a solver. The operator data member is the operator whose inverse this represents. The solver data member is the solver that will be used in applying the inverse. If the solver is null, the operator is assumed to have self-contained ability to solve systems, as for a dense matrix that does solves by factoring and backsolves.

Member Function Documentation

template<class Scalar >

void Playa::InverseOperator< Scalar >::apply	(	Teuchos::ETransp	applyType,
		const Vector< Scalar > &	in,
		Vector< Scalar >	out
	)			const [inline, virtual]

Apply the operator.

Parameters:

	applyType	Indicates whether to apply the operator, its transpose, or its conjugate transpose.
	in	The vector on which the operator is to act
	out	The vector into which the result of the operation is to be written. This vector should already be initialized by the appropriate space.
