Fmincon bfgs

WebIf the Hessian option is bfgs (the default), fmincon returns a quasi-Newton approximation to the Hessian at the final point. This Hessian can be inaccurate, as in the active-set or sqp algorithm Hessian. If the Hessian option is user-supplied, fmincon returns the user-supplied Hessian at the final point. WebThe algorithm used in fminunc for large scale problem is a trust-region method (details can be found in fminunc documentation), and the algorithm in fmincon is l-bfgs (see …
