Animated Vectors Plot with data coming from Simulink (WITH EXPLAINING IMAGES)

Hallo, I'm getting mad to understand how to do something like this : (WATCH) " http://www.energyreply.it/teoria.html " There is only one animated image in the page, well, I need to know how to do it.
Actually I only need to know how to plot animated vectors coming from a Simulink model. All the rest is easy.
My Simulink model produce two separate signals: For exemple sin(x) and cos(x) when X are a stream of values coming from a slope function from 0 to 2*pi.
How can I plot a vector (not necessarily starting from the origin of axis) and see it turning ? When I say a VECTOR I MEAN AN ARROW ! not a simple point!
I hope to be able to see an animation of an arrow that turns around a custom defined point.
And don't forget to explain how to set the speed of the animation! Sometimes happens that animation appears only for half a second!
Does anyone know how to do this?
Pleeeeese help me! I'M LOOSING THE TRUST IN MYSELF :-(

The webpage that you pointed to uses Adobe Flash to achieve with the animation - I don't know of a way to generate Adobe Flash files directly from MATLAB data.
However, you should be able to create an animated GIFs from MATLAB plots. See this File Exchange submission: Animated GIF
You first need to export your Simulink outputs to the MATLAB workspace, and then use MATLAB plotting functions.

I'm trying to solve the problem by following your instructions. I really hoped that they are sufficient. Thanks for your help. However I still hope that someone will post a small example.

I've been able to do this:
for t=1:360
hold on
corda=0.3;
r=0.3;
a=0;
b=0.2;
c=0.2;
d=0;
e=0.2;
f=0.2;
g=-0.2;
h=-0.2;
z=(-1*(r+corda));
x=(r+corda);
axis([z x z x]);
Dpercent=[0.00,1.25,2.50,5.00,7.50,10.00,15.00,20.00,30.00,40.00,50.00,60.00,70.00,80.00,90.00,95.00,100.00,100.00,95.00,90.00,80.00,70.00,60.00,50.00,40.00,30.00,20.00,15.00,10.00,7.50,5.00,2.50,1.25,0.00];
x=corda.*((Dpercent-25.00)./100);
Ypercent=[0.00,2.37,3.27,4.44,5.25,5.85,6.68,7.17,7.50,7.25,6.62,5.70,4.58,3.28,1.81,1.01,0.16,-0.16,-1.01,-1.81,-3.28,-4.58,-5.70,-6.62,-7.25,-7.50,-7.17,-6.68,-5.85,-5.25,-4.44,-3.27,-2.37,0.00];
y=r+(corda.*(Ypercent./100));
X=x.*cos(t*(2*pi)/360)-y.*sin(t*(2*pi)/360);
Y=x.*sin(t*(2*pi)/360)+y.*cos(t*(2*pi)/360);
plot(X,Y);
r1=0.*cos(t*(2*pi)/360)-r.*sin(t*(2*pi)/360);
r2=0.*sin(t*(2*pi)/360)+r.*cos(t*(2*pi)/360);
R1=[0,r1];
R2=[0,r2];
plot(R1,R2);
quiver(r1,r2,a,b);
quiver(r1,r2,c,d);
quiver(r1,r2,e,f);
quiver(r1,r2,g,h);
M(t)=getframe
clf
end
movie(M);
Now I need to esport simulation data from simulink to matlab's workspace.
I used the block "simout to workspace"
I tryed to specify that I need a simple ARRAY variable type but it LOVES to SAVE MY DATA AS:
simout <1x1x64 double>
I need a simple array made of 64 elements with my numerical value inside. My model is costant time division made so I don't need time information.
(Anyway could be usefull in tre future to know wow to obtain a two rows 64 coloumn matrix with a row for time and a row for values)
I don't know how to build a simple array from my
simout <1x1x64 double>
For exemple to use it for defining the vectors component in the animation.
I need a simple exemple of script in which you take an array made like myne (simout <1x1x64 double> coming from "simout to workspace" setted like "ARRAY" type) and use it to plot it:
Wrong exemple:
A=[1:64];
plot(A,simout);
That exemple doesn't work....
How to make it run?
Does anybody knows?
thankyou.

This script work but, anybody knows a faster way tho download the values ftom simout into A?
A=[simout(:,:,1),simout(:,:,2),simout(:,:,3),simout(:,:,4) ------------ simout(:,:,500]; B=[1:500]; Plot(B,A);
Probably it is not very difficult someone can help me?

For exemple this doesn't work
B=[1:500]; A=[VwrX(:,:,B)]; plot(B,A);
It is faster but don't work. suggestions?

That's Work grate!
A=length(simout);
B=[1:A];
ArrayOUT(1,B)=simout(:,:,B);
thank You Myself! you're Grate!
