The OS project includes a Matlab hookup to the COIN solvers including 
Cbc, Ipopt, and SYMPHONY. In the m-file containing the input data you 
specify the solver you want. If you look in OS/example/matlab you will 
see the OSMatlabSolver.cpp that gets compiled into a MATLAB .mex file to 
interface with the COIN-OR solvers and the OS library. There are example 
m-files in OS/data/matlabFiles.

If you download the OS User's Manual at

http://www.coin-or.org/OS/doc/osUsersManual_1.1.pdf

starting on page 76 you will a description of our MATLAB interface. You 
can even call solvers on a remote server by specifying a URL.  The 
result of the optimization is displayed in the MATLAB browser.

With the OS project you can call and interface with any Osi compliant 
solver. The Osi project is included in the OS download. The OS project 
also provides an interface to general nonlinear problems which Osi does 
not.

Hope this helps. Let me know if you have further questions.
