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.

Tools

Code AnalyzerIdentify and address code issues (Since R2022b)
Code Compatibility AnalyzerIdentify and address compatibility issues against current version of MATLAB (Since R2022a)
