LeftOrRight  leftOrRight,
Preconditioner< Scalar > &  rtn 
) const [pure virtual]

create an incomplete factorization.

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
leftOrRight whether this preconditioner is to be applied from the left or right
rtn newly created preconditioner, returned by reference argument.

Implemented in Playa::EpetraMatrix.
