could anyone help me how to solve the issue for the following code

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.

This question barely differs from many of your 200+ questions recently. It's becoming clear that you are not attempting at all to troubleshoot your code and your using this platform as a means of other people fixing your code. You won't learn how to code or how to analyze data this way.

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

ok.But in the graph the total number of N_UE seems to be 8. But what i actually need is the number of N_UE should be 4 which needs to be shared among two different radius.Could you please help me on this.

[KSSV]

Not clear.

[Prabha Kumaresan]

In the beginning of the code i have intialized N_UE=4,which indicates 4 number of users. So i want to have only 4 number of users which should be randomly scattered with respect to two different radius.

[KSSV]

Where you want those users to lie?

[Prabha Kumaresan]

they can be scattered randomly with respect to two different radius.

Please help me to get the graph in the attached form with respect to the code.
