Why do you have to use that specific method? Is it a classroom assignment that you need to develop your own code for based on some algorithm published in a paper or explained by your professor?

Realize that you have read the paper and you have downloaded the toolbox, and you have contact information from the authors. I haven't done any of that, so I don't know what I could add that you can't do better than me. http://matlab.wikia.com/wiki/FAQ#Can_you_program_up_the_algorithm_in_this_article_for_me_and_explain_it_to_me.3F
