Successful C/C++ code generation from MATLAB code depends on compliance with code generation rules and limitations. For example, your MATLAB code must only use MATLAB functions and toolbox functions supported for code generation. To identify and fix issues with your MATLAB code, prior to C/C++ code generation, you can use the Code Analyzer and Code Readiness Tool. To check that your MATLAB code produces generated code that works as expected, generate and execute a MEX function, which is executable and testable in the MATLAB environment.
codegen | Generate C/C++ code from MATLAB code |
coder.runTest | Run test replacing calls to MATLAB functions with calls to MEX functions |
coder.screener | Determine if function is suitable for code generation |
Workflow for Preparing MATLAB Code for Code Generation
Prepare MATLAB code for C/C++ code generation or code acceleration.
Fixing Errors Detected at Design Time
Fix errors detected by the code analyzer.
Fix Errors Detected at Code Generation Time
Fix errors and warnings listed in the code generation report.
Choose a strategy for detecting and correcting code that is not suitable for code generation.
Using MEX Functions That MATLAB Coder Generates
Accelerate your MATLAB function or test generated code for functionality and run-time issues.
Check for MATLAB code violations at design time.
Check Code with the Code Analyzer
Check for MATLAB code violations in the MATLAB Editor.
Code Generation Readiness Tool
Interpret code generation readiness tool report.
Code Generation Readiness Screening in the MATLAB Coder App
The app screens your MATLAB code for unsupported features and functions.
Check Code by Using the Code Generation Readiness Tool
Run the code generation readiness tool at the command line, from the current folder browser, or in the app.
Workflow for Testing MEX Functions in MATLAB
Test MEX functions before generating C/C++ code.
Why Test MEX Functions in MATLAB?
Test a MEX function to verify that it provides the same functionality as the original MATLAB code.
Generate MEX Functions by Using the MATLAB Coder App
Follow the workflow for generating MEX functions with the MATLAB Coder™ app.
Generate MEX Functions at the Command Line
Follow the workflow for generating MEX functions with codegen.
Check for Run-Time Issues by Using the App
Detect and fix issues that are harder to find in generated standalone C/C++ code.
Call a MEX function in the same way that you call the original MATLAB function.
Collect and View Line Execution Counts for Your MATLAB Code
See how well your test exercises MEX code generated from your MATLAB code.
Debug issues with generated MEX functions.
Unable to Determine Code Generation Readiness
The code generation readiness tool fails when it is unable to find your entry-point files.
Unable to Open a MATLAB Coder Project
Use a backup project file to revert to the format of an earlier release.
Slow Operations in MATLAB Coder App
Disable code generation readiness screening.
