the developer of OPTI I wrote most of the MEX interfaces, including the very
basic CLP interface. I have never tried the CLP SLP solver, but if you have any
questions regarding the interfacing of nonlinear solvers via MEX, then I am
happy to help. I have been following this post and it sounds like it could be
quite a bit of work to implement a general NLP interface (with a general
nonlinear objective and nonlinear constraints called back to MATLAB) using CLP.
John would be best to comment here, but typically interior point and sequential
quadratic algorithms perform better for problems with largely nonlinear
functions, than a sequential linear approach. Of course if your problem is only
mildly nonlinear (bilinear or even quadratic), then the SLP approach may also
work acceptably.<o:p></o:p></SPAN></P>
