I am currenly plotting an animation of an object with a quiver based on the x and y coordinates as well and the x nad y velocities. I was wondering if I can adjusting the tilt of a rectangle that I am plotting based on the direction of the quiver? Currently, the dimensions of the rectangle are defined as shown in the code below and it always stays facing the same direction.

for k=1:length(Ycord)
    clf
    for i=1:5
        hold on
        grid on
        plot(Xcord(k,i),Ycord(k,i),'.');
        quiver(Xcord(k,i),Ycord(k,i),Xvel(k,i),Yvel(k,i),'LineWidth',1);
        rectangle('Position',[Xcord(k,i)-1,Ycord(k,i),2,4],'EdgeColor','k','LineWidth', 1);
    end
    pause(0.1)
end
