Classi di MATLAB
È possibile utilizzare le classi di MATLAB, comprese le classi valore, le classi handle e i System object in un blocco MATLAB Function. Per saperne di più sulle classi valore e sulle classi handle in MATLAB, vedere Comparison of Handle and Value Classes. Per saperne di più sui System object, vedere What Are System Objects?.
È necessario tenere presente alcune note d'uso e limitazioni quando si utilizzano le classi in un blocco MATLAB Function.
Blocchi
| MATLAB Function | Include MATLAB code in Simulink models |
| MATLAB System | Include System object in model |
