Remarks

Values should always be positive and can be higher than 1.0. A value lower than 1.0 means that the eventual preconditioner matrix will have fewer non-zero entries as the original matrix. A value higher than 1.0 means that the eventual preconditioner can have more non-zero values than the original matrix.

Note that any changes to the FillLevel after creating the preconditioner will invalidate the created preconditioner and will require a re-initialization of the preconditioner.
