Personally I would write the results of Matlab analysis to a file in some structured format and then read that in from ChucK. This would be a two-stage process (generate data file from Matlab, read in data file and generate audio in ChucK), which makes real-time tricky/not readily possible, but I would guess that by using Matlab in the first place you are not terribly interested in real-time. The main advantage of OSC is its ease-of-use in real-time scenarios, so if youre not doing real-time you don't gain much by using it.

If you are aiming for real-time analysis+sonification, then you can ignore this suggestion entirely!

I went here and looked around a little:
http://sourceforge.net/projects/oscmex/files/
The osc-mexmaci64.zip file actually has the source code, which seems
to be cross-platform, so that should tell you the function names you
need.

I also found this small library that just sends OSC messages. It is
written in Matlab, so you don't have to mess with Mex files.

Good luck.
