<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
For basic use of the <A HREF="../SNES/SNES.html#SNES">SNES</A> solvers the user need not explicitly call
<A HREF="../SNES/SNESSetUp.html#SNESSetUp">SNESSetUp</A>(), since these actions will automatically occur during
the call to <A HREF="../SNES/SNESSolve.html#SNESSolve">SNESSolve</A>().  However, if one wishes to control this
phase separately, <A HREF="../SNES/SNESSetUp.html#SNESSetUp">SNESSetUp</A>() should be called after <A HREF="../SNES/SNESCreate.html#SNESCreate">SNESCreate</A>()
and optional routines of the form SNESSetXXX(), but before <A HREF="../SNES/SNESSolve.html#SNESSolve">SNESSolve</A>().
