How can I tell to the existing Mathworks installation where the installed documentation is?

I have installed Matlab 2023a, and later installed Offline Documentation by running

./mpm install-doc --matlabroot=/opt/MATLAB/R2023a --destination=/opt/MATLAB/R2023a_docs

However, matlab does not seem to find that installed that documentation. Is there a way to manually tell it where it is?

Make sure your follow the instructions on this page. https://www.mathworks.com/help/releases/R2023a/install/ug/install-documentation-on-offline-machines.html

Specifically

Step 2. Install Documentation on Target Machine

...

5. If you used the --destination flag to install the documentation somewhere other than the default location, go to Step 3 to modify the startup file.

Step 3. Point MATLAB to Documentation

If you used the --destination flag to install the documentation somewhere other than the default location, follow this procedure to point MATLAB to the documentation.

1. On the offline computer, open the startup.m file for editing.
2. In your startup.m file, add this line to set the documentation root to the new documentation location, where newDocInstallFolder is the path to the folder where you installed the documentation:docroot(newDocInstallFolder/help)
3. Restart MATLAB to complete documentation installation.

After Installation

Access the documentation as you normally would. If MATLAB still tries to open documentation on the web, go to the Home tab, and in the Environment section, click Preferences and select MATLAB > Help. Under Documentation Location, select Installed locally.

Thank you.

You have a problem with that line of code though. It should be, seemingly,

docroot('newDocInstallFolder/help')

otherwise matlab interprets "/" as division.

Also, this does not seem to work: Even though

docroot

ans =

    '/opt/MATLAB/R2023a_docs/help'

, searching for something in the help browser results in "No internet connection".

Just copy/pasting from the documentation page I linked to.

Also, did you follow the instructions in "After Installation"? Starting in R2023a, MATLAB is set to use the online documentation by default. Follow those steps to switch that to use local documentation.

[Lockywolf]

The switch to "local documentation" is, indeed, there, but it resets to "online documentation" automatically after a restart. And if I switch it to "offline documenation", it is saying "not installed".

It's probably time to recommend contacting support.
