PCASASetTolerances

Sets the convergence thresholds for ASA algorithm

Synopsis

PetscErrorCode  PCASASetTolerances(PC pc, PetscReal rtol, PetscReal abstol,PetscReal dtol, PetscInt maxits)
Collective on PC

Input Parameter

pc - the context
rtol - the relative convergence tolerance (relative decrease in the residual norm)
abstol - the absolute convergence tolerance (absolute size of the residual norm)
dtol - the divergence tolerance (amount residual can increase before KSPDefaultConverged() concludes that the method is diverging)
maxits - maximum number of iterations to use

Notes

Use PETSC_DEFAULT to retain the default value of any of the tolerances.
