Hi admin,  
I am new to Vienna system level simulator. All the scenarios in the launcher file expect basicScenario shows error, when running the simulation. I wonder if someone here can help to find where is the actual error.

Dear jansh,

Do you mean, you are able to run “launcherExample.m” successfully but not the other launcher files? Have you followed the steps in the quick start guide?

If yes, what simulator and MATLAB versions are you using? What is the error message and is it the same for all the other launcher files?

Regards,  
Charmae

Hi Charmae,  
Thank you for your response. I figured out the problem, I am using MATLAB 2019a and it does not have the “Statistics and Machine Learning Toolbox”. All the examples in the launcher files use the poissrnd functions, which requires the above mentioned toolbox.
