I have an external toolbox (created by me) and I want to disable it (not uninstall it), do some stuff, and then re-enable it.
I have looked through the available methods in matlab.addons.toolbox, but I only see options for installing and uninstalling.
Looking at other ideas, removing the paths would be a way to disable the toolbox, but how do I know (programatically) what paths to remove? Looking in the Add-Ons explorer I can see the paths associated with the toolbox and I have an option to diasble it, but I can't get either of those through the matlab.addons.toolbox API.
I think I either need a way to get the paths for the toolbox, or I need a method that allows me to disable it.
Am I missing something that exists today to do this?

Does matlab.addons.disableAddon do what you want?

@Cris LaPierre, looks like your URL got messed up? My "correction" did, too, when I tried the same way. Here it is without separate name for the link: https://www.mathworks.com/help/matlab/ref/matlab.addons.disableaddon.html

disableAddon is exactly what I wanted. I just never thought to explore up a level, I was stuck at matlab.addons.toolbox.
Thanks!

Thanks. I've updated it.

Holy smokes I didn't know such a thing was available, but it's been a long time since I looked.
Prior to R2017b, was there a way to do the same?

I do not know. I assume you picked that release because you noticed on the doc page that this was introduced in R2017b.

Yes. This sort of functionality is something I've looked for before, but I would have been running R2009b, R2012a or R2015b at the time. I still do compatibility checking in older versions.
The addons manager in R2015b doesn't even have an option to enable/disable products in the GUI, so maybe that's part of underlying changes to the addons system.

Another way is you could remove the toolbox folder(s) from the path with rmpath

In order to do that, I need to know what path the toolbox is installed at. I can see that in Add-Ons explorer, but I havent seen the associated paths in any output from the command line add-on methods.

Use the path variable in your code:
mp = path % store the MATLAB path in variable mp.
% Then search it to find and remove the toolbox folders.
% Stick new path back into path
path = savepath(mp)
Finding the folders and deleting them from the variable is probably more complicated than the other solution given to you.

I would be guessing at whether a path belongs to the installed toolbox or not. And I cannot use any known structure about the particular toolbox's paths, because the actual reason I am using this code is to remove old paths from the MATLAB path that point to defunct (old) installations of the same toolbox.
In order to use the remove path method, I would need to know explicitly which paths are there because of the installed toolbox.
As you mentioned though, disableAddon is exactly what I wanted and is far more robust.
