I'm running an executable in the following order, so i could close it after a certain time is passed:

system([exe_name ' &']);% Open executable

if time>time_th

system(['TASKKILL -f -im "' exe_name '"']); % Close executable

When i use the kill command, the executable stops running, but the cmd window stays open for unknowen reason.

I don't want to "kill" cmd windows because we may have another necessery cmd window open in the background.

How can I kill the executable while making sure that I'm closing also the cmd window?

在 MATLAB Online 中打开

You could try to start the executable through Java instead of opening a CMD window:

runtime = java.lang.Runtime.getRuntime();
process = runtime.exec('exename');  % non-blocking
...
process.destroy();
% Might be useful:
% rc = process.waitFor();    % block Matlab until external program ends
% rc = process.exitValue();  % fetch an ended process' return code
