PCPostSolve#

Optional post-solve phase, intended for any preconditioner-specific actions that must be performed after the iterative solve itself.

PetscErrorCode PCPostSolve(PC pc, KSP ksp)

Input Parameters#

pc - the preconditioner context
ksp - the Krylov subspace context

Sample of Usage#

    PCPreSolve(pc,ksp);
    KSPSolve(ksp,b,x);
