Running .exe file from MTLAB using system()

Hi everyone,

I use system to run my executable file:

system('myfile.exe')

The problem that I'm facing is that it doesn't go to next line unless I close the GUI (which the exe file opens). The exe file doesn't need an input so all I want is to run the exe file programmatically and move on to the next line without waiting for an action from the user. Can anybody help me please? I'd be grateful.

As per the tip section system's help: to execute the operating system command in the background, include the trailing character, &, in the command argument. Therefore:

system('myfile.exe &');

Thank you but I've tried that; it closes the GUI and opens a DOS page. That's not what I want._

Works fine for me with, for example, notepad:

system('notepad.exe')

notepad opens and matlab waits for it to be closed.

system('notepad.exe &')

notepad opens, matlab returns to the command prompt and notepad stays open.

What's special about your GUI? Does it communicate with matlab?

You're right, it worked! Because I'm using which to find the path of the exe file, I'd made a mistake in the way I should add & to the string. Now it does what you described:

fileexe_path = which ('gravity_app.exe')
system_command_string = [fileexe_path, ' &']
status = system (system_command_string)

Thank you very much for your help.
