On Windows you can set the position of the Mouse cursor with:
  set(0, 'PointerLocation', [X, Y]);
More flexible and most likely working on Linux and MacOS also:
  robot = java.awt.Robot;
  robot.mouseMove(X, Y)
  robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
  robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);

Good luck, Jan
