I have been using the SDK provided for MatLab and have compiled the program. However when I run freetrack.mexw32 I always get the error:
"First call to function...
...loading FreeTrackClient.
Unable to find 'FTReportID' function
??? Error using ==> freetrack
Failed to load FreeTrackClient...Terminating"
How can I solve this problem? I have placed the mexw32 file in the main directory of freetrack so it can find the dll files, but it cannot load the function specified.

This might be too late....
But I only encountered the error a few weeks ago myself....
The trick is to replace the line...
reportID = (importReportID)GetProcAddress(hinstLib, "FTReportID");
with...
reportID = (importReportID)GetProcAddress(hinstLib, "FTReportName");
in the freetrack_mex_interface.c file.
This also causes issues if you're also using the C SDK code, which has the same error.

I am interested in you results of these projects. I am trying to do the same thing; interfacing FreeTrack to Matlab and I managed to compile the C files and run the MEX file.
I can run functions like 'about' and 'provider', but when I run the 'getData' funciton, Matlab crashes and says "MATLAB has encountered an internal problem and needs to close". I wonder if you ever came up to this problem and what you did about it?
[edit: I seems now that, it occures when FreeTrack is running while calling the function. When i close Matlab, close FreeTrack and start Matlab only and run the function, it results in:
"Nothing returned from FTGetData
a =
yaw: []
pitch: []
roll: []
x: []
y: []
z: []
dataID: []"]
I am also interested in your results.
