%Need to be able to simulate a keypress in GUI matlab script

%Below is the simplified code segment for how keypress are collected and processed. Later in a diffenent function I need to be able remotely press the "space" key to call "pauseCallback(this);". In C, I would use ungetc(), and I did try a dos command but it failed becuase it opens in a different shell than matlab. Also, if you simplay make the call in the later function, which will need to repeated, it will eventually fail from stack overflow. I looked at everything I could find, but to no avail, any ideas here would be greatly appreciated, Thank you.

%Add Keyboard Processor - Hot Key Commands entered from keyboard
h_keyboard = this.FigureHandle;
set(h_keyboard,'KeyPressFcn',@keyproc);
function keyproc(src,event)
  disp(event.Key);
    if event.Key == "space"  %% Stop/Start Audio Playback
      pauseCallback(this);
  end
end
