WebFeb 15, 2024 · I obtained very good results with lsqnonlin (trust-region-reflective), but now my problem has both bounds and inequality constraints, which is why I have to switch to fmincon. If both bounds and inequality constraints are present, I can not use trust-region-reflective algorithm anymore.
