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.

Datos de simulación
- Save Simulation Data
Save simulation data for analyzing and debugging a model. - View and Access Logged Simulation Data
View and access saved simulation data for a completed or paused simulation. - Data Format for Logged Simulation Data
You can use many formats for logged data, includingDataset, MATLABtimeseries, arrays, and structures. Supported data formats vary between different logging techniques. However,Datasetformat is available for all logging techniques. - Log Data to the Workspace and a File Using the Record Block
Use the Record block to log data to the workspace, to a file, or to both the workspace and a file. - Convert Data to Dataset Format
To convert a workspace variable that contains data that was logged in a format other thanDatasetformat to useDatasetformat, use aSimulink.SimulationData.Datasetconstructor. - Samples to Export for Variable-Step Solvers
Control how much output the simulation generates when your model uses a variable-step solver. Use the Output options configuration parameter.
Registro de señales
- Save Signal Data Using Signal Logging
Capture signal data from a simulation by marking signals you want to log in the model. - Override Signal Logging Settings
For a specific simulation run, override the signal logging settings for individual signals marked for logging. - View the Signal Logging Configuration
View the signals that are marked for signal logging. - Visualize and Access Signal Logging Data
View and access the signal logging data for a completed or paused simulation. - Access Logged Signals with Spaces and Newlines in Logged Names
