Specify whether you want to display Code Analyzer message indicators, such as the underlining of code and the message indicator bar, for documents open in the Editor.

For more information, see Check Code for Errors and Warnings Using the Code Analyzer.

Specify the type of coding issues that you want to have underlined.

Regardless of the underlining menu option you choose, the Editor marks errors and warnings in the message indicator bar.

Provides a link to a preference panel that enables you to adjust the color highlighting errors and warnings that MATLAB can autofix. You trigger autofix by clicking the Fix button in a Code Analyzer message.

Select the set of message settings to use. Click the down arrow to select or browse to a previously saved settings file.
