运行多个仿真

为模型提供一组输入，并使用这些输入和 parsim 或 batchsim 函数运行多个仿真。

对于涉及多个并行仿真和记录大量数据的工作流，您可以使用 Simulink.SimulationInput 对象数组创建仿真集。SimulationInput 对象有助于您运行多个不同的仿真，而无需更改您的模型。SimulationInput 对象的数组使您能够运行多个仿真。

如果您拥有 Parallel Computing Toolbox™ 许可证，则可以使用 parsim 函数并行运行仿真。此函数可将多个仿真分发给并行工作进程，从而缩短整体仿真时间。带有 Parallel Computing Toolbox 的 parsim 还可以自动创建并行池、识别文件依存关系，并管理用于进行 Accelerator 和 Rapid Accelerator 仿真的工件。如果没有 Parallel Computing Toolbox 许可证， parsim 命令将串行运行多个仿真。

另外，您还可以将 batchsim 与 Parallel Computing Toolbox 和 MATLAB^® Parallel Server™ 许可证结合使用。使用 batchsim 时，仿真会将其工作负载分散到一个计算群集上。您可以打开一个单独的 MATLAB 会话来访问作业和结果。

特色示例

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: 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.
