Closing an .exe application

I am having an issue with closing an application which is currently open; I am using this code ..

fileexe_path = which ('Myo Data Capture.exe');
system_command_string = [fileexe_path, ' &'];
status = system (system_command_string);
pause(3);
TASKKILL /? -f -im Windows Command Processor.exe;

Which after 3 Seconds should close the application, (Windows Command Processor) is the name of the application in the task manager.

The Following error is showing;

Undefined function or variable 'TASKKILL'.

Error in CalibrationRoutine (line 19) TASKKILL /? -f -im Windows Command Processor.exe;

You need to pass the command you want to run to system as a complete string.

system('taskkill /? -f -im Windows Command Processor.exe')

Do you mean:

system('TASKKILL -f -im "Windows Command Processor.exe"');

? The "/?" is not useful here.

Do you really want to kill the the "Windows Command Processor" task? This sounds strange. I'd expect that you want to kill "Myo Data Capture.exe". A hard kill after 3 seconds is dangerous in every case: What happens, if you get an email notification, the hard disk optimizing starts and an Windows Update slows down the computer? There must be a better trigger for killing than a fixed interval of time.
