To set Help preferences:
On the Home tab, in the Environment section, click Preferences. Select MATLAB > Help.
Adjust the preference options as described in the table.

If your preference is set to view web documentation, but your internet connection becomes unavailable, MATLAB® changes the preference to view the installed documentation. You can reset the preference after your connection is restored.
Changes to this preference apply only to new Help browser tabs.
Select the products to include for viewing and searching documentation in the Help browser or Function browser.
If your Documentation Location is set to view documentation on the web, then you can select Show products that are not installed to select and access documentation for all MathWorks® products.
When the Help browser is already open, changes to this preference apply only to new Help browser tabs.
|Quick Help Display||
Specify whether help links display content in the Help browser or in a small window. This preference applies to reference pages or program help that you access using:
Links to reference pages from the Current Folder browser always open in the Help browser.
|Language (selected non-English systems only)|
Specify whether you want documentation in the Help browser and context-sensitive help to appear in English. Installed non-English documentation is not always current.
This option is only available if your Documentation Location is set to view documentation on the web, and for selected non-English systems only.
