Help Preferences

To set Help preferences:

  1. On the Home tab, in the Environment section, click Preferences. Select MATLAB > Help.

  2. Adjust the preference options as described in the table.

Documentation Location

Specify whether to view the documentation on the web at (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 Install Documentation. 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 Help browser is already open, changes to this preference apply only to new Help browser tabs.

Selected Products

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.

If 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:

  • Help on Selection in context menus or F1

  • Function hints or the Function Browser

  • Links in error messages

Language (selected non-English systems only)

Specify whether documentation in the Help browser and other help windows appears in your system language or in English.

This option is available for selected non-English systems only. For more information, see Translated Documentation.

To adjust the font size in the Help browser, use the Ctrl+Plus (+) and Ctrl+Minus (-) keyboard shortcuts. On macOS systems, use the Command key instead of the Ctrl key.
