Dear IPOPT team,

Thank you very much for your excellent code. I am currently interfacing IPOPT v3.12.9 using the OPTI Toolbox on an 64bit windows machine, but I have few ideas on how to access dual variables during iterations. I would appreciate it very much if you can give me some advice.

Thank you very much for your time and consideration.
