virtual void Playa::ICCFactorizableOp< Scalar >::getICCPreconditioner	(	int	fillLevels,
		int	overlapFill,
		double	relaxationValue,
		double	relativeThreshold,
		double	absoluteThreshold,
		Preconditioner< Scalar > &	rtn
	)		const [pure virtual]

create an incomplete factorization.

Parameters:

fillLevels	number of levels of fill on the local processor
overlapFill	number of levels of fill on remote processors
relaxationValue	fraction of dropped values to be added to the diagonal
relativeThreshold	relative diagonal perutrbation
absoluteThreshold	absolute diagonal perturbation
rtn	newly created preconditioner, returned by reference argument.

Implemented in Playa::EpetraMatrix.
