Sir,

I am not sure but try the similar code as below:

w=3; %width

h=2; %height

x=0.2;y=1; %corner position

xv=[x x+w x+w x x];yv=[y y y+h y+h y];

figure(1), plot(xv,yv);axis equal;

%rotate angle alpha

R(1,:)=xv;R(2,:)=yv;

alpha=30*2*pi/360;

XY=[cos(alpha) -sin(alpha);sin(alpha) cos(alpha)]*R;

hold on;plot(XY(1,:),XY(2,:),'r');

axis([-2 4 0 5])

thanks i will try it.
