Programatically close the simulation manager

Hello,

Is there a way to programmatically close the simulatiion manager in MATLAB (I am using MATLAB 2023b)?

I was only able to find this: https://nl.mathworks.com/help/simulink/slref/simulationmanager.html using closeSimulationManager function, however, is it only available from MATLAB 2025a version?

Kind regards,

[Dhruv]

While the closeSimulationManager command is mentioned in MATLAB R2025a documentation, it is in fact available from MATLAB R2024a onwards.

HI @Markos,

In MATLAB R2023b, there is no supported function or handle to programmatically close the Simulation Manager.

If you want to prevent multiple Simulation Monitor windows from popping up, you can consider using 'ShowSimulationManager' option for 'sim' or 'parsim'.

simOut = sim(in,'ShowSimulationManager','off');
% or
out = parsim(in, 'ShowSimulationManager','off', 'ShowProgress','on');

This completely avoids creating the window that you'd otherwise have to close manually .

If you need the Simulation Manager to stay visible, enable Reuse Window in its toolbar. This ensures subsequent runs reuse the same window instead of opening new ones each time.

You may refer to the below MATLAB Answers post to know more about the same:

I hope this helps you!
