Webfmincon uses a Sequential Quadratic Programming (SQP) method. In this method, a Quadratic Programming (QP) subproblem is solved at each iteration. An estimate of the Hessian of the Lagrangian is updated at each iteration using the BFGS formula (see fminunc, references , ). Webfmincon, gradient-based, nonlinear constrained, includes an interior-point, sqp, active-set, and trust-region-reflective method. linprog, linear programming problems. intlinprog, mixed-integer linear programming problems. quadprog, quadratic programming problems.
