Edit your question so that your code is formatted properly and appears within a code block by using the Code Toggle tool [more info].

In addition to reformatting your code to make it easier for us to read and understand, please explain why you believe something is wrong in this code.

Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support using the telephone icon in the upper-right corner of this page so we can investigate.
