Help Settings

You can customize how MATLAB^® displays documentation using Help settings, including whether to open web or locally installed documentation and, on some non-English systems, what language to display the documentation in.

To open the Help settings, on the Home tab, in the Environment section, click Settings. Select MATLAB > Help and adjust the settings options as described in the table below.

Setting		Usage
Documentation Location		Specify whether to view the documentation on the web at https://www.mathworks.com/help (recommended) or the documentation installed locally on your system. Viewing the web documentation requires an internet connection. The documentation is not installed as part of a MATLAB or other product installation. (since R2023a) If you set the documentation location to Installed locally and MathWorks® documentation is not installed on your system, you can install it by clicking the Install Documentation button. If you run MATLAB on a system with no internet connection (permanently offline), you can download the documentation on a computer connected to the internet and then install it on your system. For more information, see Install Documentation. If the documentation is already open in your system web browser, changes to this setting apply only to new tabs.
Language		Specify whether the installed documentation and other help windows appears in your system language or in English. Before R2024b: Use the Language option to change the documentation language in the Help browser. Supported languages include English, Japanese, Korean, Chinese, Spanish, French, Italian, or German. For more information, including how to change the language for the documentation that opens in your system web browser, see Translated Documentation.

To adjust the font size of the documentation, adjust the zoom settings for your system web browser.
