Ejecutar varias simulaciones

Proporcione la colección de entradas al modelo y utilícelas para ejecutar múltiples simulaciones con las funciones parsim y batchsim o el panel Multiple Simulations en Simulink^®

Para los flujos de trabajo que implican múltiples simulaciones paralelas 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 las simulaciones de aceleradores y aceleradores rápidos. 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.

Para empezar, consulte Running Multiple Simulations y Run Parallel Simulations for a Thermal Model of a House Using parsim.

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.
