How to generate all paths or directories that are actually used by a script?

2 views (last 30 days)
Sometimes the paths contains more than necessary directories for my script.
It is very tedious to get exact which function/script is from which path.
Now I want to run a script, and let Matlab record all the directories it ever visisted/referred in its path, and show it to me so I can simplify the path setting.
Will this be something alreay existed in Matlab?

Hi Jiansong,
Please refer to dbstack functionality. You can see the location of the functions by setting breakpoints at those functions. Use the "-completenames" option to get the full path of the functions. Below is the snippet from the documentation:
It should help in getting the path to which a function belongs.

Hi Pranav,
This dbstack doesn't seem to help.
as an example, I have a script(A), not even a function, it calls a few other scripts and functions(B) while excuting. How do I know which path was used during excuting script(A)?
In the 'set path' UI, I added a lot of folders, inherenting from colleagues's setups. And I'm sure there are a lot of path overlapping each other. My goal is simplifing/reducing the paths to its minimum. If Matlab can keep a actual path record when excuting script(A), then I can just use that record in 'set path'.
Would this be possible?
