delete the (1), (2) & (3) after cross function and place it inside as shown

 quiver3(position(1), position(2), position(3), ...
     normalAcceleration * cross(velocity(1), acceleration(1)), normalAcceleration * cross(velocity(2), acceleration(2)),...
     normalAcceleration * cross(velocity(3), acceleration(3)), 'g', 'LineWidth', 1.5);
