could anyone help me to execute the following code as i am unable to get the result.

UE=[2 4 6 8 10];
SC=[20 40 50 60 80];
for t=1:length(UE)
for r=1:length(SC)
G=rand(UE(t),SC(r));
B=zeros(UE(t),SC(r));
N=2;
for g=1:SC(r)
    C= B(:,g);
    zeroidx = find(~C);
    replaceidx = zeroidx(randperm(numel(zeroidx), N-sum(C)));
    C(replaceidx) = 1 ;
    S(:,g) = [C];
end
Z = G .* S
end
end

Not sure what this code does but you need to pre-allocate matrix S.

i.e.

UE=[2 4 6 8 10]; 
SC=[20 40 50 60 80]; 
for t=1:length(UE) 
    for r=1:length(SC) 
        G=rand(UE(t),SC(r));
        B=zeros(UE(t),SC(r)); 
        S = B;
        N=2; 
        for g=1:SC(r) 
            C= B(:,g); 
            zeroidx = find(~C); 
            replaceidx = zeroidx(randperm(numel(zeroidx), N-sum(C))); 
            C(replaceidx) = 1 ; 
            S(:,g) = C; 
        end
        Z = G .* S;
    end
end

thanks but in the command window it is getting displayed as matrix dimensions must agree in the command line Z=G.*S

Not when I copy and paste that code. That code executes for me.

I do notice, though, that you overwrite all of Z for each t and r value. If you are going to overwrite it all, why bother calculating it?
