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

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?
