Krylov Methods - KSP Manual Pages#


The scalable linear equations solvers (KSP) component provides an easy-to-use interface to the combination of a Krylov subspace iterative method and a preconditioner (in the KSP and PC components, respectively) or a sequential direct solver. KSP users can set various Krylov subspace options at runtime via the options database (e.g., -ksp_type cg). KSP users can also set KSP options directly in application by directly calling the KSP routines listed below (e.g., KSPSetType() ). KSP components can be used directly to create and destroy solvers; this is not needed for users but is intended for library developers. Manual Pages Table of Contents
