Dear all,<br>
<br>
I am using IPOPT, and I would like to test other Hessian approximation
(sparse one).<br>
<br>
To get the data I need, I implemented the <b>intermediate_callback </b>function<b>.
</b>Through the <b>IpoptCalculatedQuantities* ip_cq, </b>I can have
the vector of the Lagrangian like this:<br>
<br>
<b>SmartPtr<const Vector> x = ip_cq->curr_grad_lag_x();</b><br>
<br>
I can know the size of this vector like this:<br>
<br>
<b>size = x->Dim();</b><br>
<b><br>
</b>But I do not know how I can know the values of each component of
this vector<b><br>
<br>
</b>I checked the help and the <b>IpVector.hpp</b> file but I did not
find anything<br>
<br>
Does anybody know how to do it ?<b><br>
</b><br>
best regards<br>
<br>
