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.

PreferenceUsage
Documentation Location

Specify whether to view the documentation provided with your installed products or the documentation on the web at http://www.mathworks.com/help. Viewing the web documentation requires an internet connection and a MathWorks® Account.

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.

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.

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:

  • Help on Selection in context menus or F1

  • Function hints or the Function Browser

  • Links in error messages

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.

To adjust the font size in the Help browser or MATLAB Web browser, use the Ctrl + Mouse Scroll keyboard shortcut.
