function[] = ServoAngleNew(Theta1,Theta2)
pause(2);
a = arduino('COM4');
s = servo(a,9,'MinPulseDuration',7.50e-4,'MaxPulseDuration',2.4e-3);
s = servo(a,10,'MinPulseDuration',7.50e-4,'MaxPulseDuration',2.4e-3);
writePosition(s, Theta1);
writePosition(s, Theta2);
end
i want to move my robot arm with 2 servos and when i call ServoAngleNew with 0 or 1 my arm does not moves correctly, simply do a tremulous. i try to drive one servo and works two or three servos do not move, any help??? thanks

That two second pause sounds too long to me. Also, you should create the arduino object and servos outside the function and pass them in to the function, which should concentrate on updating the position. You are recreating the server objects every time with this code.
