Debugging and Analysis

Diagnose problems, check syntax and release compatibility

As you work in the Editor and Live Editor, MATLAB^® automatically identifies potential coding problems. Debugging features help you diagnose specific issues. Additionally, you can generate reports that help you update your code when you upgrade to a newer MATLAB release.

Topics

Debugging

Debug MATLAB Code Files

Diagnose problems in MATLAB code files using different debugging methods.

Set Breakpoints
Examine Values While Debugging

Add Reminders to Files

Annotating a file makes it easier to find areas of your code that you intend to improve, complete, or update later.

Editor/Debugger Preferences

Use Editor/Debugger preferences to customize the Editor.

Syntax Checking

Check Syntax as You Type

Some entries appear in different colors in the Command Window, the Editor, and the Live Editor to help you identify MATLAB elements. This is known as syntax highlighting.

Check Code for Errors and Warnings Using the Code Analyzer

Use the MATLAB Code Analyzer to check your code for coding problems automatically.

MATLAB Code Analyzer Report

Generate a report that identifies potential errors, problems, and opportunities for improvement in your code.

Code Analyzer Preferences

Set Code Analyzer preferences to enable or disable Code Analyzer features and specify message indicator preferences.
