Public Methods

virtual void Apply (I *X, I *Result)
 Apply returns R(*Result) with respect to the boundary conditions of (*X).

virtual void Preconditioner (I *X, I *Result)
 if one wants to solve an operator equation with this operator, one can provide a preconditioner.

virtual void InversePreconditioner (I *X, I *Result)
 the BiCGStab2 solver also needs the inverse operation.

virtual double DiagonalEntry (int *level, Wavelets *W)
 often the DiagonalEntry is needed for preconditioners.

virtual void NotUsing (I *X)
 the solvers check whether the temporary data used by them is also used for the evaluation of the operator; this is avoids wrong numerical results.
