Hi,<div> Firstly, <span style="color:rgb(34,34,34);font-size:13px;font-family:arial,sans-serif">I'm sorry for bothering you with this mail. But if you could solve my problems, I would appriciate you for your reply.</span><br>
<div> I have a question about the usage of ipopt matlab win32 interface. If I implement the callback routine for evaluating the Hessian Matrix, the Hessian callback function will take as input the current value of the variables <b>X</b>, the factor in front of the objective term <b>Sigma</b>, the values of the constraint multipliers <b>Lambda</b>. But in the output struct <b>Info</b>, there is only the field of <b>Lambda</b> without the field of <b>Sigma</b>. So I wonder that how could I get the final value of the factor <b>Sigma</b> or the proportional relationship between <b>Lambda</b> and <b>Sigma</b>.</div>
<div> <span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Thank you for your reading. Hoping your reply.</span><br clear="all">
