What Is Optimization Toolbox?

fminbndoutput-1 Algorithm was terminated by the outputfunction.-2 The bounds are inconsistent.Structure containing information about theoptimization. The fields of the structure areiterationsfuncCountalgorithmmessageNumber of iterations takenNumber of function evaluationsAlgorithm usedExit messageOptionsOptimization options used by fminbnd. Youcanuseoptimset to set orchange the values of these fields in the options structure options. See“Optimization Options” on page 6-8 for detailed information.DisplayFunValCheckMaxFunEvalsMaxIterOutputFcnLevel of display. 'off' displays no output; 'iter'displays output at each iteration; 'final' displaysjust the final output; 'notify' (default) displaysoutput only if the function does not converge.Check whether objective function values are valid.'on' displays an error when the objective functionreturns a value that is complex or NaN. 'off'displays no error.Maximum number of function evaluationsallowed.Maximum number of iterations allowed.Specify one or more user-defined functions that anoptimization function calls at each iteration.
