Guardar datos en tiempo de ejecución de la simulación

Guarde los datos de la simulación en el espacio de trabajo de MATLAB^®; registre las señales; exporte los datos de señal, tiempo, salida y estado

Puede guardar los valores de la señal en el espacio de trabajo de MATLAB, o en un archivo MLDATX, MAT o Excel^® durante la simulación para su posterior recuperación y procesamiento. Guardar los datos de la simulación también se conoce como registrar o exportar los datos de la simulación.

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. El uso del formato Dataset almacena los datos como objetos timeseries de MATLAB, que puede procesar con MATLAB.

El registro de señales y los almacenes de datos utilizan el formato Dataset.
La salida y el registro de estado utilizan Dataset como formato predeterminado.
El formato predeterminado para guardar los bloques To File o y To Workspace es Timeseries.

Simulink^® proporciona herramientas para convertir los datos registrados en formato Dataset.

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