PEPRefine

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

See section Iterative Refinement for a discussion of the different refinement strategies.
