Webfmincon(), as you mentioned, employs several strategies that are well-known in nonlinear optimization that attempt to find a local minimum without much regard for whether the global optimum has been found. If you're okay with this, then I think you have phrased the question correctly (nonlinear optimization). WebMar 19, 2024 · Solutions are guaranteed to satisfy the bounds. There is no assurance that all constraints (linear or non-linear) will be satisfied. ... For the default 'interior-point' …

Maximum number of function evaluations allowed. full_output bool, optional. If True, return optional outputs. disp int, optional If non-zero, print messages. WebOct 26, 2013 · 'trust-region-reflective' requires you to provide a gradient, and allows only bounds or linear equality constraints, but not both. The documentation for your call to fmincon says: x = fmincon(fun,x0,A,b) starts at x0 and attempts to find a minimizer x of the function described in fun subject to the linear inequalities A*x ≤ b. x0 can be a ...
