How to find directory path for MATLAB add-ons from script

Hi, I have a script that will be run by multiple users on different computers. For it to run, it needs this directory path:

'C:\Users\name of user\AppData\Roaming\MathWorks\MATLAB Add-Ons\Toolboxes\'

It seems to be the same for every computer except for "name of user". I was wondering if there was a way to access this path dynamically without having every individual using it to manually change the name in the path.

Thanks.

See https://www.mathworks.com/help/matlab/matlab_env/get-add-ons.html#buy5hl8-1 for documentation of the location of the folder.

As to where it is stored:

In prefdir, file matlab.mlsettings is an OpenXML document, which means it is a compressed heirarchy of XML related files.

Inside that, file fsroot/settingstree/matlab/addons/settings.json has groupName":"addons" with key InstallationFolder

I will poke around more to see if I can find a way of accessing it more nicely.

Found it

matlab.internal.addons.util.retrieveAddOnsInstallationFolder

ans = "/.Add-Ons"

This is exactly what I was looking for. Thank you!

Further note for future reference:

https://www.mathworks.com/help/matlab/ref/matlab.addons.install.html

is the command line tool to install an add-on that you have the mltbx file for.
