I would like to turn off the following behavior: When I try to open a mfile that doesn't exist as far as MATLAB knows*, MATLAB creates an empty mfile with that name in the present directory and opens it. Instead, when I try to open a non-existing file I would like MATLAB to return an error with no new file created. What setting do I have to change?
*Example of when this happens: I am editing mfile1 which calls mfile2. I don't realize mfile2 is not on my path. In mfile1's editor I use CNTRL-D to try and open mfile2. Since mfile2 is not on my path, it doesn't open: instead a new blank mfile2.m is created in the current directory and opened in the mfile editor.
