For other readers who are new to 'Spectral Unmixing', this is a good overview.

Sandhya, I dont think there are any out of the box approaches. Your best bet is to read up on some of the algorithms noted in the wiki link and look for functions to perform the constituting steps.

Or, after you understand the basics of some of the algorithms, look for existing MATLAB packages like this which implement them for you.
