Student at the Simon Fraser University. I am working on a research which requires the nonlinear optimization.<br><br>I would like to use Ipopt. I have tried the pre-complied binaries for Windows (C++) and read the examples.<br>And I found that Ipopt require the input of Jacobian Matrix and the Hessian of the Lagrangian before the calculaion of the optimization.<br>Because one of the requirement of my program is to allow it can be more interactive.<br>I can not predefine the Jacobian Matrix and the Hessian of the Lagrangian for all constraints, because the constraints will be changed at different situations.<br>Do there exist any method to compute these matrix from the set of provided constraint functions automatically?<br><br>Thank you very much for
your help.<br><br>Best regards<br>Lewis<br></pre></div>
