The Matlab interface for the Fortran version of Ipopt is not part of the 
Ipopt package on COIN-OR, and I don't know any details about it.  Please 
contact the authors of that package.
(I assume you are talking about this:

The latest release of Ipopt contains a contribution from Peter Carbonetto, 
who wrote a Mex (matlab) interface for the C++ version of Ipopt, see

https://projects.coin-or.org/Ipopt/wiki/MatlabInterface

However, I don't think anybody has tried it on Windows yet...(?)  At some 
point I had a look at the following link, which seemed to be helpful:

I hope this helps,
