Weboptimoptions ( 'fmincon') returns a list of the options and the default values for the default 'interior-point' fmincon algorithm. To find the default values for another fmincon algorithm, set the Algorithm option. For example, opts = optimoptions ( 'fmincon', 'Algorithm', 'sqp') WebMaxIter Option: This option is used when we want to specify the maximum number of iterations in the respective algorithm. The required parameter and its value is separated …
Weboptions = optimset('GradObj','on') then the function funmust return, in the second output argument, the gradient value g, a vector, at x. Note that by checking the value of nargoutthe function can avoid computing gwhen funis called with only one output argument (in the case where the optimization algorithm only needs the value of fbut not g).
