It doesn't work well yet. It works for some cases, but others not,
giving different errors (erroneous solution, LAPACK errors or
nonconvergence). My test so far has been an identity preconditioner,
which should be the same as not preconditioning at all. I need to do
some more testing though, perhaps with Jaocbi instead.
