When I'm setting a path in MatLab and try to save my changes so I don't have to set it everytime I get the error message:
|
MATLAB cannot save changes to the path.

The path file, pathdef.m, might be read-only or might be in a directory for which you do not have write access.

You can save pathdef.m to a different location. In order for MATLAB to use that pathdef.m in future sessions, you need to save it in your MATLAB startup directory (the direcotry from which you start MATLAB).

Would you like to save pathdef.m to another location?

So I click yes and save in in the start up directory and it just sends me the same message again.

Thanks for the help

Do you have write access to your MATLAB startup directory? What platform are you running MATLAB on?

Dear Chris,

You forgot to ask a question. I assume, that you want to get write-privilegs for the folder PATHDEF.M is saved in. If you work on a multi-user system, it is better to use a PATHDEF.M file for each user, therfore Matlab suggests to copy it to a user-related folder.
If you mention your Matlab version, OS and your initial workpath, we could give some more advices.

Kind regards, Jan

I just tried what you suggested by saving it to a user-related folder and it worked! Thanks for the help
