<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/KSP/index.html "><small>Report Typos and Errors</small></a></div>
<H2> Krylov Methods - KSP: : <A HREF="../../../src/ksp/ksp/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 KSP and
<A HREF="../../../docs/manualpages/PC/index.html">PC</A>
components, respectively) or a sequential direct solver. KSP users can set various Krylov
subspace options at runtime via the options database (e.g.,
<font face ="Courier">
-ksp_type cg
</font face>
).
KSP users can also set KSP options directly in application
by directly calling the KSP routines listed below (e.g.,
<A HREF="../../../docs/manualpages/KSP/KSPSetType.html">KSPSetType()</A>
).
KSP components can be used directly to create and
destroy solvers; this is not needed for users but
is intended for library developers.
