Featured Examples

Model Advisor

The capabilities of the Model Advisor to check a model or subsystem for conditions and configuration settings that can result in inaccurate or inefficient simulation of the system represented by the model or generation of inefficient code from the model. The Model Advisor produces a report that lists all the suboptimal conditions or settings that it finds, suggesting better model configuration settings where appropriate.

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.

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.
