NEPConvergedReason

Reason a nonlinear eigensolver was determined to have converged or diverged.

Synopsis

typedef enum {/* converged */
              NEP_CONVERGED_TOL                =  1,
              NEP_CONVERGED_USER               =  2,
              /* diverged */
              NEP_DIVERGED_ITS                 = -1,
              NEP_DIVERGED_BREAKDOWN           = -2,
                    /* unused                  = -3 */
              NEP_DIVERGED_LINEAR_SOLVE        = -4,
              NEP_DIVERGED_SUBSPACE_EXHAUSTED  = -5,
              NEP_CONVERGED_ITERATING          =  0} NEPConvergedReason;

Values

• NEP_CONVERGED_TOL - converged up to tolerance

• NEP_CONVERGED_USER - converged due to a user-defined condition

• NEP_DIVERGED_ITS - exceeded the maximum number of allowed iterations

• NEP_DIVERGED_BREAKDOWN - generic breakdown in method

• NEP_DIVERGED_LINEAR_SOLVE - inner linear solve failed

• NEP_DIVERGED_SUBSPACE_EXHAUSTED - run out of space for the basis in an unrestarted solver

• NEP_CONVERGED_ITERATING - the solver is still running
