Vérification de code
Après avoir généré le code, inspectez le code source et les résultats en sortie pour les vérifier. Le rapport de génération de code offre une interface interactive permettant d’inspecter les fichiers sources C/C++, les types de données générés et d’autres informations sur le code. Accédez de manière programmatique à un sous-ensemble des informations du rapport de génération de code avec l’objet d’informations de rapport. Vous pouvez tester la sortie du code MEX généré par rapport au code MATLAB® d’origine ou créer des tests personnalisés basés sur les classes de tests unitaires MATLAB. Vous pouvez choisir de générer des vérifications d’erreurs run-time qui vous alertent si des erreurs se produisent pendant l’exécution du code.
