<div id="version" align=right><b>petsc-3.7.5 2017-01-01</b></div>
<div id="bugreport" align=right><a href="mailto:petsc-maint@mcs.anl.gov?subject=Typo or Error in Documentation &body=Please describe the typo or error in the documentation: petsc-3.7.5 v3.7.5 docs/manualpages/PC/index.html "><small>Report Typos and Errors</small></a></div>
<H2> Preconditioners - PC: <A HREF="../../../src/ksp/pc/examples/tutorials/index.html">Examples</A></H2>
The
<A HREF="../../../docs/manualpages/KSP/index.html">Scalable Linear Equations Solvers (KSP)</A>
component provides an easy-to-use interface to the combination of
a Krylov subspace iterative method and a preconditioner (in the
<A HREF="../../../docs/manualpages/KSP/index.html">KSP</A> and PC
components, respectively) or a sequential direct solver.
KSP users can set various preconditioning
options at runtime via the options database (e.g.,
<font face ="Courier">
-pc_type jacobi
</font face>
).
KSP users can also set PC options directly in application
codes by first extracting the PC context from the KSP context via
<A HREF="../../../docs/manualpages/KSP/KSPGetPC.html">KSPGetPC()</A>
and then directly calling the PC routines listed below (e.g.,
<A HREF="../../../docs/manualpages/PC/PCSetType.html">PCSetType()</A>
).
PC components can be used directly to create and
destroy solvers; this is not needed for users but
is for library developers.
