Dati di dimensione variabile
Definizione e differenze per la generazione di codice
È possibile specificare le variabili nei blocchi MATLAB Function e MATLAB System come dimensione variabile, ovvero dati la cui dimensione non è nota in fase di compilazione o cambia in fase di esecuzione.
Blocchi
| MATLAB Function | Include MATLAB code in Simulink models |
| MATLAB System | Include System object in model |
Funzioni
coder.areUnboundedVariableSizedArraysSupported | Check if current configuration settings allow unbounded variable-size arrays (Da R2024a) |
coder.varsize | Resolve size incompatibility errors and declare upper bounds |
