I can't read it. Please have one line of code per line. Please read this and fix your post: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Please:

Reduce the code down to a minimal working example (MWE) that reproduces the error. Note that this might actually solve the problem, but if it doesn't, then edit your post:
Format the code to be more readable.
Describe what is being run, what you expect, what you get.

And please use a more descriptive title than "I get an error, could you guys help me to figure out?"
