This question is closely related to:
Executing the following command in Matlab (R2019a) causes a not repsponding error in my external program to appear
cmdStr1 = ['"C:\Program Files (x86)\SGeMS\sgems-x64.exe"']
Using the answer in [1] from:

I can successfully get Matlab (R2019a) to execute my program using the following
cmdStr2 = ['set path=%path:C:\Program Files\MATLAB\R2018b\bin\win64;=% & "C:\Program Files (x86)\SGeMS\sgems-x64.exe"']
However as soon as I include the arguments
cmdStr3 = ['set path=%path:C:\Program Files\MATLAB\R2018b\bin\win64;=% & "C:\Program Files (x86)\SGeMS\sgems-x64.exe" -s']
I get the initial not responding error again.
This appears to be an issue with Matlab as I can execute the command successfully in the command line.
Note, using the suggestion of dos() from Image Analyst results in the same error
Any help would be appreciated!

Can you move with your current MATLAB directory to that folder and do this
Would that call the software?
You can try this answer as well if the above doesn't work properly.

Hi @MarioMalic, problem solved thanks to your assistance. The program runs with system('POSC2.exe'); I changed the path to the program and that's it.

That's great to hear. Usually, you wouldn't run the program from its directory. You should try it from some other directory where you're writing the code. Probably, the software could not be opened maybe due to the read/write access in the current directory, as any files that program generates (session file), will be within the current directory of MATLAB.
I just wanted to check whether it's possible to call it within the program folder. This might indicate an issue with your paths, or r/w access as mentioned above.
