Matlab freezes on startup

Hello all ,Matlab freezes on startup. It opens a file named dos.m, and from that point, I can neither run any script, set the path, nor even navigate to a folder. any idea ?

That it opens dos.m in the Editor and then freezes could indicate that your startup.m file is telling it to open that file in the Editor. It is not obvious what would be causing it to freeze after that.

Open startup.m in the Editor (or any text editor) to see what the problem is.

The fix could be that edit (making appropriate changes to the file), or creating a new startup.m file to do what you want.

nop, MATLAB still opens but the status states 'Initializing' or 'Busy' for a long time.

At this point, it might be appropriate to uninstall and then reinstall MATLAB. The startup file problem is the only possibility I can think of that could cause that behaviour, however that seems now not to be the situation.

(Consider saving all your user files to a back-up directory, although that may not be absolutely necessary.) You will probably need to regenerate your preferences directory as well.

Another option is to contact Technical Support:

Although they will most probably support reinstalling the software.
