What Is Optimization Toolbox?

Defining the ProblemLinear System of EquationsObjective function (required) is the function describing a system ofnonlinear equations you want to solve. Specify the function as a functionhandle of the form @objfun, whereobjfun.m is an M-file, or as an anonymousfunction. For a description of this M-file, see the “Input Arguments” on page8-108 section of the function reference page.Derivatives specifies if the Jacobian is supplied in the objective function or ifit should be approximated by the solver.Start point (required) is the initial point (vector) for the algorithm.Function EquivalentFor the function that corresponds to this solver and more information on theproblem definition, see the fsolve function.fzero Problem SetupFunction to MinimizeEquation (required)isthefunctionwhosezeroistobecomputed. Specifythe function as a function handle of the form @objfun, whereobjfun.m is anM-file, or as an anonymous function. For a description of this M-file, see the“Input Arguments” on page 8-124 section of the function reference page.Interval containing zero of equation has two options. You must eitherenter your own interval using the fields X1 and X2 or specify a point X toenable the algorithm to find an interval containing that point for you. Toenter your own, select Specify interval [X1, X2] and enter the values for5-19
