Greetings,

Whenever I download repositories from my team from other departments they have scripts which are runned from a path which contain ".." and I do not know how to change on my MATLAB workstation the parent path for it. For example:

MODEL_CONFIG='..\03_config\config.m';

run(MODEL_CONFIG)

On their workstation this code works but on my workstation it says that:

"there is no ..\03_config\config.m not found."

and I know that the ".." is the parent directory from the project. My question is:

"How can I change the default parent directory so that ".." can work on my workstation too?

You can change the startup folder; see https://www.mathworks.com/help/matlab/matlab_env/matlab-startup-folder.html

The effect of this is that when you start MATLAB, MATLAB would automatically cd() to that directory.

I do not generally recommend this, except for the case where you have moved your hierarchy of MATLAB files to an unusual location.

Ok. I used "userpath" and finally found my default path and if a change that to corelate with the ".." It works, but the problem is that I cannot change the userpath to match my desired path.

For example my user path is:

C:\Documents\MATLAB

but my project parent directory is in:

C:\Documents\MATLAB\Projects\99_OEM_GSM\

So right now if I change in the scripts ( which are a lot ! )

MODEL_CONFIG='..\03_config\config.m';

to

MODEL_CONFIG='..\Projects\99_OEM_GSM\03_config\config.m';

it works. But I would really like to globaly change the userpath or the realitve path from this C:\Documents\MATLAB to this C:\Documents\MATLAB\Projects\99_OEM_GSM\ so that I do not need to modify any of the script file.

Actually I am stupid. ".." is like "cd.." in MS-DOS.... I was in the wrong folder all the time. I am not supposed to be in the parent directory of the project when I run the main script. I am supposed to be in the folder directory where the main script is running (main.m).

So when I am in the folder directory of the main.m file the following link:

MODEL_CONFIG='..\03_config\config.m';

says go back with one folder from where the main.m file is and there should be the folder 03_config which you access. Thank you guys.

And if you have more subfolders in the folder in which is the main.m script "." - means the current location....
