WebPositive exit flags correspond to successful outcomes. Negative exit flags correspond to unsuccessful outcomes. The zero exit flag corresponds to the solver being halted by exceeding an iteration limit or limit on the number of function evaluations (see Iterations and Function Counts, and also see Tolerances and Stopping Criteria). WebThe number of iterations in an optimization depends on a solver's stopping criteria. These criteria include several tolerances you can set. Generally, a tolerance is a threshold which, if crossed, stops the iterations of a solver. Set tolerances and other criteria using optimoptions as explained in Set and Change Options.
