Hello All,

I have a matlab code that consists of a for loop. The for loop iterates from 1 up to 2000. During each iteration, it plots an object through a patch command. The coordinate matrices updates afterwards in each iteration. Meaning I can see the object moving in the plot window.

My question is, how do I implement the same code in Simulink?

So far, I have tried with the 'For iterator Subsystem' in a fixed-step simulation. However, the for iterator subsystem iterates for a number of times in a single steps. Where as I need an ouput matrix with each iteration of 'For iterator Subsystem' that I can use as an input to patch command.

for zu=1:2000
[SowjEcken_neu]=Sowjet_Bewegung(SowjEcken_neu,SowjEcken,SowjFlaechen,SowjFlaechen2,rx,ry,rz,sT) 
[Ecken_neu]=USA_Bewegung(Ecken_neu,Ecken,Flaechen1,Flaechen2,Flaechen3,T,rx,ry,rz)
newplot
     %USA
     patch ('Vertices',Ecken_neu,'Faces',Flaechen1,'FaceColor',[0 0 1])
     
     patch ('Vertices',Ecken_neu,'Faces',Flaechen2,'FaceColor',[0 0 1])
     
     patch ('Vertices',Ecken_neu,'Faces',Flaechen3,'FaceColor',[0 0 1])
     %SOWJET
     patch ('Vertices',SowjEcken_neu,'Faces',SowjFlaechen,'FaceColor',[1 1 0])
     patch ('Vertices',SowjEcken_neu,'Faces',SowjFlaechen2,'FaceColor',[1 0 0])
  
    A=60;
    axis ([-A A -A A -A A])
    view(3)
    drawnow
    
    %Parameter-USA
    rz = rz+0.1;
    rx = rx+0.2;
    ry = ry+0.1;
    w=w+0.01;
    l=-24*sin(w);
    p=21*cos(w);
    k=0;
    T(1:3,4) = [l;p;k];
    
    %Parameter-Sowjet
    sw=sw+0.02
    sl=25*sin(sw);
    sp=0;
    sk=34*cos(sw);
    sT(1:3,4) = [sl;sp;sk];
    %Hintergrundfarbe
    fig = gcf;
    fig.Color = [0.5 0.5 0.5];
