Ejecutar varias simulaciones
parsim y batchsim o el panel Multiple Simulations en Simulink®Para los flujos de trabajo que implican múltiples simulaciones en paralelo y el registro de muchos datos, puede utilizar la función parsim o batchsim, o ejecutar las simulaciones con el panel Multiple Simulations en el editor de Simulink.
Si dispone de una licencia de Parallel Computing Toolbox™, puede utilizar la función parsim para ejecutar las simulaciones en paralelo. La función distribuye múltiples simulaciones a workers paralelos para acelerar el tiempo total de simulación. Utilizar la función parsim con Parallel Computing Toolbox permite automatizar la creación de pools paralelos, identifica las dependencias de los archivos y gestiona los artefactos de construcción para simulaciones en modo Accelerator y Rapid Accelerator. La función parsim ejecuta simulaciones en serie si no se dispone de una licencia de Parallel Computing Toolbox.
Puede utilizar la función batchsim con las licencias de Parallel Computing Toolbox y MATLAB® Parallel Server™. Cuando se utiliza la función batchsim, las simulaciones se descargan en un cluster de proceso. Puede abrir una sesión separada de MATLAB para acceder al trabajo y a los resultados.

Use Multiple Simulations Panel to Run Design Study with Different Parameter Values
Use the Multiple Simulations panel in the Simulink® Editor to run multiple simulations with varying values of stiffness of the suspension for a road profile that has a sinusoidal shape.
Parallel Simulations Using Parsim: Parameter Sweep in Normal Mode
Run multiple simulations of a Monte Carlo study in parallel by using Parallel Computing Toolbox™. Parallel execution leverages the multiple cores of your host machine to run many simulations more quickly. These simulations could also be run in parallel on computer clusters using the MATLAB® Parallel Server™. This example will work even if the Parallel Computing Toolbox™ or the MATLAB Parallel Server is not available, but the simulations will run in serial.
Parallel Simulations Using Parsim: Parameter Sweep in Rapid Accelerator Mode
Run multiple simulations of a Monte Carlo study in parallel by using Parallel Computing Toolbox™. Parallel execution leverages the multiple cores of your host machine to run many simulations more quickly. These simulations could also be run in parallel on computer clusters using the MATLAB® Parallel Server™. This example will work even if the Parallel Computing Toolbox™ or the MATLAB Parallel Server is not available, but the simulations will run in serial.
Parallel Simulations Using Parsim: Test-Case Sweep
Run multiple Simulink® simulations corresponding to different test cases in the Signal Editor block using SimulationInput objects and the parsim command. The parsim command uses Parallel Computing Toolbox™, if it is available, to run simulations in parallel, otherwise the simulations are run in serial.
Rapid Accelerator Simulations Using Parsim
The use of Rapid Accelerator in applications that require running parallel simulations for a range of input and parameter values.
Multiple Simulations Workflow Tips
The goal of this example is to provide helpful tips for running multiple simulations using parallel simulation tools. This example will work even if the Parallel Computing Toolbox™ is not available, but the simulations will run in serial. We will be using the model sldemo_suspn_3dof.
