Well Windows 7 can't open rar extensions - it says "Windows can't open this file." On my work computer when I needed to open a rar file once I had to search around and finally stumbled upon 7zip. I installed that and it opened fine. I don't have 7zip on my home computer, though maybe I should. I'm just saying that uploading standard zip files would make it easier for people so they don't have to install another software package. I didn't even bother to download his file except just now (after your message) to verify (again) that Windows in fact can't open a rar file. Apparently even though Windows uses a .zip extension when it compresses files, it does not use Winzip.

I don't have the MATLAB file and copying and pasting produced errors which I'm sure are different than yours. I don't have the data file, though I guess I could create it from the data you supplied. And I don't have the error - you forgot to tell us. So all of that leads me to suggest you solve it yourself with the debugger. It will actually be the fastest way to solve it rather than debugging via messages to the Answers forum.
