Enthaltene Beispiele
Ausführen ausgewählter „Model Advisor“-Prüfungen und Generieren eines Berichts
Dieses Beispiel zeigt, wie Sie ausgewählte „Model Advisor“-Prüfungen für ein Simulink-Modell programmatisch ausführen, die Ergebnisse einzelner Prüfungen abrufen und einen HTML-Bericht mit einer Zusammenfassung der Ergebnisse erstellen. In diesem Workflow wird im Beispiel auf unverbundene Leitungen und nicht übereinstimmende Einheiten innerhalb des Modells geprüft. Dies trägt dazu bei, potenzielle Modellierungsprobleme und Komplexität zu erkennen.
Analyze Simulation Execution Using Simulink Profiler
Identify issues that can contribute to poor simulation performance.
Run Test-Case Sweep Using Parallel Simulations
Run multiple Simulink® simulations corresponding to different test cases using batchsim and Parallel Computing Toolbox™. The batchsim function offloads simulations to a compute cluster, freeing up your local machine so you can continue working while the batch job is processing. While parsim is useful for running parallel simulations on local resources, batchsim is useful for running a large number of computationally expensive simulations. If you do not have Parallel Computing Toolbox, the simulations in this example will run serially.
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.
