#include "slepcnep.h" PetscErrorCode NEPSetRefine(NEP nep,NEPRefine refine,PetscReal tol,PetscInt its)Logically Collective on NEP
nep | - the nonlinear eigensolver context | |
refine | - refinement type | |
tol | - the convergence tolerance | |
its | - maximum number of refinement iterations |
-nep_refine <type> | - refinement type, one of <none,simple,multiple> | |
-nep_refine_tol <tol> | - the tolerance | |
-nep_refine_its <its> | - number of iterations |
The tol and its parameters specify the stopping criterion. In the simple method, refinement continues until the residual of each eigenpair is below the tolerance (tol defaults to the NEP tol, but may be set to a different value). In contrast, the multiple method simply performs its refinement iterations (just one by default).
