Detailed Description

template<class Scalar>
class Thyra::DefaultInverseLinearOp< Scalar >

Concrete LinearOpBase subclass that creates an implicit LinearOpBase object using the inverse action of a LinearOpWithSolveBase object.

This class represents an implicitly inverse linear operator:

 
 M = inv(A)

where A is any LinearOpWithSolveBase object. Specifically, the solve(...) function A is used to implement this->apply() and the solveTranspose(...) function A is used to implement this->applyTranspose().

SolveCriteria objects can be associated with A to define the solve criterion for calling the A.solve(...,fwdSolveCriteria) and A.solveTranspose(...,adjSolveCriteria).

) 
 

Initialize given a non-const LinearOpWithSolveBase object and an optional .

Parameters:
lows [in] The LinearOpWithSolveBase object that will solve(...) and/or solveTranspose(...) will be called on. Note that *this may give up non-const views of *lows so that *lows may be changed through clients of this object.
fwdSolveCriteria [in] The criteria used to call lows->solve(...). If fwdSolveCriteria==NULL then the default solve criteria built into *lows will be used. If fwdSolveCriteria!=NULL then *fwdSolveCriteria will be copied internally. Warning! If shallow copy is used by any parameters in fwdSolveCriteria->extraParameter these these parameters will be "remembered" by *this.
adjSolveCriteria  [in] The criteria used to call lows->solveTranspose(...). If adjSolveCriteria==NULL then the default solve criteria built into *lows will be used. If adjSolveCriteria!=NULL then *adjSolveCriteria will be copied internally. Warning! If shallow copy is used by any parameters in adjSolveCriteria->extraParameter these these parameters will be "remembered" by *this.
Preconditions:
  • lows.get() != NULL
