[Ipopt] Ipopt and MATLAB (fwd)

[Benjamin S. Skrainka]

I forgot to mention that if you are using MacTex (a popular LaTeX
distribution for OS/X),
there is another application called mex in /usr/texbin which conflicts
with the MATLAB mex command.
I had to specify the absolute path to the mex in the MATLAB .app.

Thanks for making IPOPT available!

Cheers,

Ben
