WebJul 15, 2016 · ExitFlag = -2 No feasible solution found. fmincon stopped because the size of the current step is less than the selected value of the step size tolerance but constraints are not satisfied to within the selected value of the constraint tolerance. The 'non-good' results deviate about 2% of the optimal solution and correspond to ExitFlags 2 and -2 ...

How to choose DiffMinChange value? - MATLAB Answers

WebSep 8, 2013 · The purpose of DiffMinChange and DiffMaxChange is purely to let the user tune and try to improve the accuracy of the gradient/Hessian approximations. It goes without saying, I guess, that if you make a really lousy approximation to the derivatives, your step size (and step direction) can be very different from what you would get if you turned ... WebDiffMinChange is an option for controlling finite difference steps the solver takes to estimate derivatives. It does not directly relate to the step size that the solver takes in its iterations. Usually it is safe to ignore this option, but if you are optimizing a simulation or ODE, consult Optimizaing a Simulation or ODE.
