Remarks

The values should always be positive and can be larger than 1.0. A low value will keep more small numbers in the preconditioner matrix. A high value will remove more small numbers from the preconditioner matrix.

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