Code Verification
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.
