The type of Newton iterative refinement.

Synopsis#

typedef enum { PEP_REFINE_NONE,
               PEP_REFINE_SIMPLE,
               PEP_REFINE_MULTIPLE } PEPRefine;

Values#

PEP_REFINE_NONE - no refinement
PEP_REFINE_SIMPLE - refinement of each converged eigenpair individually
PEP_REFINE_MULTIPLE - refinement of the invariant pair as a whole

Note#
