Fmincon bounds

Webfmincon is careful to obey bounds when estimating both types of finite differences. So, for example, it could take a backward, rather than a forward, difference to avoid evaluating at a point outside bounds. WebMar 5, 2024 · In this case: output.stepsize >> ans = 6.586e-4. The estimated minima was at x = [6.457e-4, 6.457e-4] and the lower bounds you've permitted are [0 0], so the solver …
