<H3><FONT COLOR="#883300">Notes</FONT></H3>
If the user sets trackall=PETSC_TRUE then the solver computes (or estimates)
the residual norm for each eigenpair approximation. Computing the residual is
usually an expensive operation and solvers commonly compute only the residual
associated to the first unconverged eigenpair.
<P>
The options '-eps_monitor_all' and '-eps_monitor_draw_all' automatically
activate this option.
