You can change how Code Analyzer messages appear in the Editor and Live Editor. With a few exceptions, these preferences apply to messages in the Editor, Live Editor, MATLAB® Function Block Editor (if your products use that tool), and Code Analyzer Report.
On the Home tab, in the Environment section, click Preferences. Select Code Analyzer, and then adjust preference options as described in the table below.
|Enabled Integrated Warning and Error Messages|
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 Automatically Check Code in the Editor and Live Editor — 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.
