NEPRefine#

The type of Newton iterative refinement.

Synopsis#

typedef enum { NEP_REFINE_NONE,
               NEP_REFINE_SIMPLE,
               NEP_REFINE_MULTIPLE } NEPRefine;

Values#

NEP_REFINE_NONE - no refinement
NEP_REFINE_SIMPLE - refinement of each converged eigenpair individually
NEP_REFINE_MULTIPLE - refinement of the invariant pair as a whole

Note#

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