Detailed Description

template<class Scalar>
class TSFExtended::InverseOperator< Scalar >

TSFInverseOperator 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 >

RCP< const Thyra::VectorSpaceBase< Scalar > > TSFExtended::InverseOperator< Scalar >::domain ( ) const [inline, virtual]

Return the domain of the operator.

Definition at line 123 of file TSFInverseOperatorImpl.hpp.

template<class Scalar >

void TSFExtended::InverseOperator< Scalar >::generalApply	(	const Thyra::EOpTransp	M_trans,
		const Thyra::VectorBase< Scalar > &	x,
		Thyra::VectorBase< Scalar > *	y,
		const Scalar	alpha = `1.0`,
		const Scalar	beta = `0.0`
	)		const `[inline, virtual]`

Compute alpha*M*x + beta*y, where M=*this.

Parameters:

M_trans	specifies whether the operator is transposed: op(M) = M, for M_trans == NOTRANS op(M) = M', for M_trans == TRANS
x	vector of length this->domain()->dim()
y	vector of length this->range()->dim()
alpha	scalar multiplying M*x (default is 1.0)
beta	scalar multiplying y (default is 0.0)
