Web20.2 Minimizers. fminbnd is designed for the simpler, but very common, case of a univariate function where the interval to search is bounded. For unbounded minimization of a function with potentially many variables use fminunc or fminsearch. The two functions use different internal algorithms and some knowledge of the objective function is ...

WebJan 27, 2024 · In this situation, you would want to have DerivativeCheck='on' for 6 different runs. To run the finite differencing baseline, however, your proposal would force the user to set both SpecifyObjectiveGradient=false and DerivativeCheck='off'. Some people would prefer just to set SpecifyObjectiveGradient=false and not to have to fuss with additional …
