Code Verification

Behavioral verification of generated code, traceability, code generation reports

After you generate code, inspect the source code and output results for verification purposes. The code generation report provides an interactive interface for inspecting the generated C/C++ source files, generated data types, and other code insights. Access a subset of information from the code generation report programmatically by using the report information object. You can test the output of generated MEX code against the original MATLAB® code, or you can create custom tests based on the MATLAB unit test classes. You can choose to generate run-time error checks that alert you to errors that occur during code execution.
