It can be open by two apps, as long as the first app didn't put a lock on it. For example, open a csv file in notepad or wordpad, and you can still do whatever you want with it in some other app. Though the first app will have a "snapshot" of what it looked like when it read it in - it won't update "live" as the other app changes it. Some apps, such as MATLAB, will recognize when the file on disk has changed. For example open a text file in the editor and then in wordpad and change it and save it in wordpad. Then when you return to MATLAB, it will say the file has changed on disk and ask if you want to reload it.
I don't know if MATLAB's fopen() puts a lock on the files. You could easily check though.

Most likely every row does not have the same format. Look at line 15 and see how it differs from line 14.
