Answer
Hi Venkat,

the LMI toolbox is part of the Robust Control Toolbox and is actually called LMI Lab. If you have the Robust Control Toobox the you also have the LMI Lab. You can see whether you have it by looking the help files on you Matlab software. If you don't have it, then there isn't a free *legal* way to acquire it. You must pay for it. Of course you should also have a valid Matlab license to do that.
See the following link for more info on the Robust Control Toolbox:

Look for the "Introduction to Linear Matrix Inequalities".
