Hi Punit,
You are correct, the Tobii Analytics SDK does not support the Tobii EyeX Controller hardware since they belong to different product lines (research/analysis vs. gaming/consumer applications). For the same reason, there is no ongoing initiative from Tobii when it comes to Matlab bindings for the EyeX Controller.
However, I know that some other developers out there are experimenting with using the EyeX SDK together with Matlab. For example, you can check out this forum thread.
