Web9 rows · You can specify optimization parameters using an options … WebOptions. fminunc uses these optimization parameters. Some parameters apply to all algorithms, some are only relevant when using the large-scale algorithm, and others are only relevant when using the medium-scale algorithm.You can use optimset to set or change the values of these fields in the parameters structure, options.See Optimization Parameters, …
WebFor a description of the other options, see optimset. To initialize an options structure with default values for fminsearch use options = optimset ("fminsearch"). fminsearch may also be called with a single structure argument with the following fields: objective.

WebOct 13, 2024 · Essentially, fminsearch has a problem because the point [0,0] is a stable point on the surface, where the gradient is exactly zero. So your function is perfectly flat there, and fminsearch becomes confused, because the initial simplex is small enough that the function appears close enough to constant that it gives up.
