Why is MATLABWindow.exe spawned when launching MATLAB in batch mode?

When starting MATLAB 2026a in batch mode

matlab.exe -wait -batch "run(some_script.m); exit"

it spawns MATLABWindow.exe.

If the script called uses the parallel toolbox, MATLAB seemingly spawns 3 MATLABWindow.exe instances per worker.

Why is this happening and, most importantly, can it be prevented?

According to the documentation starting MATLAB with the flag '-batch'

• Starts without the desktop
• Does not display the splash screen

Why would we need MATLABWindow.exe in this situation?

Try adding "-noFigureWindows" to the startup command...
