WebJan 30, 2024 · In regards to number of iterations, you should always check the state of the optimizer after optimizing. Observing some state like maximum number of iterations reached always calls for a different parameterization (e.g. increasing the upper-limit) or reformulation of the problem. – sascha Jan 30, 2024 at 16:11 Add a comment 3 1 0 WebMay 2, 2012 · I have some measured data stored in vectors "x" and "y".

Weboptimset: Configures and returns an optimization data structure. Description This function creates or updates a list which can be used to modify the behaviour of optimization methods. The goal of this function is to manage the options list with a set of fields (for example, 'MaxFunEvals', 'MaxIter', etc...). Weboptimset with no input or output arguments displays a complete list of parameters with their valid values. options = optimset (with no input arguments) creates an options structure …
