Générer du code
La génération de code C/C++ est la fonctionnalité centrale de MATLAB® Coder™. Vous pouvez générer du code à partir de l’application en ouvrant celle-ci avec coder ou bien à partir de la ligne de commande avec la fonction codegen. L’application vous guide pas à pas dans le processus de génération de code, notamment en vous indiquant les bonnes pratiques et en affichant des aides visuelles claires pour les paramètres et les options. Le workflow de la ligne de commande offre un moyen simple, reproductible et efficace de lancer la génération de code. Le workflow de génération de code supporte de nombreux types de données, y compris les données de taille variable et globales. Il supporte également les fonctions de point d’entrée (de haut niveau) multiples, la génération de fonctions MEX à plusieurs signatures (MEX polymorphe) ainsi que la personnalisation de propriétés fondamentales comme la disposition et l’indexation des tableaux dans le code généré. Par ailleurs, il permet de générer du code qui utilise des fonctionnalités clés du langage C++ telles que les classes, les namespaces et la surcharge de fonction.
