MATLAB: Could anyone help me how to solve the issue for the following code

graph

code:
N_UE=[4];
N_SC=[12];     
    Xmax=1 
    Ymax=1 
        radius=2
        xsd=ones(1,N_UE)*Xmax
        ysd=ones(1,N_UE)*Ymax
        rrx=radius*sqrt(rand(1,N_UE))
        thetarx=2*pi*rand(1,N_UE)
        xrx=xsd+rrx.*cos(thetarx) 
        yrx=ysd+rrx.*sin(thetarx)
        th = 0:pi/100:2*pi
        xunit = radius * cos(th) + Xmax
        yunit = radius * sin(th) + Ymax
            figure
            plot(xunit, yunit)
            hold on
            plot(ysd,xsd,'r^')
            hold on
            plot(yrx,xrx,'ko')
            hold on
The above code works fine: i am getting the graph. Could anyone help me how to get the graph with respect to two different radius such that 4 users need to be present in total.

Best Answer

N_UE=[4];
N_SC=[12];
Xmax=1
Ymax=1
R=[2 3] ;
for i = 1:length(R)
    radius = R(i) ;
    xsd=ones(1,N_UE)*Xmax
    ysd=ones(1,N_UE)*Ymax
    rrx=radius*sqrt(rand(1,N_UE))
    thetarx=2*pi*rand(1,N_UE)
    xrx=xsd+rrx.*cos(thetarx)
    yrx=ysd+rrx.*sin(thetarx)
    th = 0:pi/100:2*pi
    xunit = radius * cos(th) + Xmax
    yunit = radius * sin(th) + Ymax
    figure(1)
    plot(xunit, yunit)
    hold on
    plot(ysd,xsd,'r^')
    hold on
    plot(yrx,xrx,'ko')
    hold on
end
