// The first of these classes deals
// with parameters for the linear
//
// In particular, the ILUT takes
// the following parameters:
- // -ilut_fill: the number of extra
- // entries to add when forming the ILU
- // decomposition
- // -ilut_atol, ilut_rtol: When
- // forming the preconditioner, for
- // certain problems bad conditioning
- // (or just bad luck) can cause the
- // preconditioner to be very poorly
- // conditioned. Hence it can help to
- // add diagonal perturbations to the
- // original matrix and form the
- // preconditioner for this slightly
- // better matrix. ATOL is an absolute
- // perturbation that is added to the
- // diagonal before forming the prec,
- // and RTOL is a scaling factor $rtol
- // >= 1$.
- // -ilut_drop: The ILUT will
- // drop any values that
- // have magnitude less than this value.
- // This is a way to manage the amount
- // of memory used by this
- // preconditioner.
