WebIn Table 2, we give the numerical comparison of Method 1 with fmincon, which is a MATLAB tool box for constrained optimization. We use the sequential quadratic programming (SQP) method in the fmincon tool box to solve Example 1 by p = 1.1 and the same initial points. WebYou should be able to use 'fmincon' in the following syntax: x = fmincon (fun,x0, [], [], [], [],lb, [],nonlcon) x0 is a three element vector and the result will also be in the same format which will give you the values for x,y and z.
