Starting in R2021a, when you run MATLAB with an internet connection, the Help browser displays the web documentation by default. When you run MATLAB on a system without an internet connection, or if your internet connection becomes unavailable, the Help browser displays the installed documentation instead.
To change the default documentation location, on the Home tab, in the Environment section, click Preferences. Select MATLAB > Help and change the Documentation Location.
I would like to know what is the code to change the documentation location programmatically.
I thought it was something like
com.mathworks.mlservices.MLHelpServices.setDocCenterDomain
but I could not find it
Thank you in advance
Marco

Hi Marco,
This is controlled by the matlab.help.DocCenterLocation setting. The valid values are "WEB" or "INSTALLED":
>> s = settings;
>> s.matlab.help.DocCenterLocation.PersonalValue = 'WEB';
Please note that this not a documented functionality and might not work in future releases.
Hope it Helps

I confirm that for some unknow reason, the following property:
s.matlab.help.DocCenterLocation21a.PersonalValue='INSTALLED'
or
s.matlab.help.DocCenterLocation21a.TemporaryValue ='INSTALLED'
works only if you restart MATLAB. It would be nice if this was not necessary.
It also would be nice if this instant effect could become a feature request in a future MATLAB release.
