component provides an easy-to-use interface to the combination of
12
a Krylov subspace iterative method and a preconditioner (in the KSP and

components, respectively) or a sequential direct solver. SLES users can set various Krylov
15
subspace options at runtime via the options database (e.g.,

SLES users can also set KSP options directly in application
21
codes by first extracting the KSP context from the SLES context via

and then directly calling the KSP routines listed below (e.g.,

KSP components can be used directly to create and
27
destroy solvers; this is not needed for users but
28
is intended for library developers.
