Guardar datos en tiempo de ejecución de la simulación

Guarde los datos de simulación como salida, señal, tiempo, estado y datos de registro de almacén de datos

Durante la simulación, puede guardar los datos de simulación en el área de trabajo de MATLAB^® o en un archivo, incluyendo archivos MLDATX, MAT o Excel^® para su posterior recuperación y procesamiento. Los datos de simulación pueden incluir cualquier combinación de salida, señal, tiempo, estado y datos de registro de almacén de datos.

Guardar los datos de simulación en formato Dataset simplifica el procesamiento posterior proporcionando un formato común a los resultados de una variedad de técnicas de registro. Usar el formato Dataset almacena los datos como objetos timetable o timeseries de MATLAB, que se pueden procesar con MATLAB.

Para determinar qué enfoque utilizar para registrar los datos, consulte Save Simulation Data.
