I am developing a GUI application in Matlab R2018b. This C:\Windows\system32\cmd.exe window pops up and won't go away. It is causing problems. What causes it to pop up and how do you get rid of it?

If you're talking about a compiled application rather than in the MATLAB development environment, then use mcc with the -e option.

Hi,
One of the probably reasons for the cmd.exe window to pop up is you are using
!
somewhere in your code.
If this is not the case, you can see which statement in your code is causing the window to pop-up by adding the breakpoints to it and using Step/ Step-in/ Step-out buttons available in the debugger.
