WebDec 12, 2012 · It's still questionable whether DiffMinChange would make a difference for FMINCON algorithms where line searches are involved. The finite difference calculations normally control the direction of the search for the next point, but not the step size. If the step size isn't large enough to skip over the locally flat region, then you'll still get ...

WebOct 23, 2013 · 2) If you find that your target parameter is indeed influencing your forward calculation result, you might need to set the "DiffMinChange" option to certain larger values (e.g. 10% of parameter value or else, according to your sensitivity analysis).The default DiffMinChange value is usually too small if your parameter is less sensitive. In such … pain behind ear when lying downWebDiffMinChange 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.
