Hi all,<br>
<br>
I am currently using IPOPT through the MATLAB interface. Since I have<br>
rather complex functions, the Jacobians and Hessians are being<br>
calculated automatically using INTLAB's automatic differentiation<br>
feature. However, I am at times finding INTLAB difficult to use, since<br>
it does not support direct use of some built-in functions such as<br>
interp1 and atan2.<br>
<br>
I've also tried out ADiMat, but couldn't get the source code<br>
transformation routine to work (due to search path problems). I also<br>
tried ADiMat's finite difference function, which worked but was<br>
extremely slow and thus I couldn't adopt it.<br>
<br>
I would like to hear recommendations for other automatic differentiation<br>
tools/setups which you found useful. Thanks.<br>
<br>
Best regards,<br>
Andrew Spiteri<br>
