how to implement two different scenarios in the same code.

scenario 1: 
   N_rng=[1 2 23]
   for s=1:length(N_rng)
   this_seed = N_rng(s);
   fprintf('Below results are for rng = %d\n', this_seed);
   rng(this_seed);
   unused_rows=1:N_UE(t);
   while ~isempty(unused_rows)
   N_UE_rows=2;
   if (N_UE_rows+1)==numel(unused_rows);
   N_UE_rows=numel(unused_rows);
   end
   rows=unused_rows(randsample(length(unused_rows),N_UE_rows))
   [~,idx]=find(ismember(unused_rows,rows));
   unused_rows(idx)=[];
   end
   end
scenario 2:
N_rng=[1 2 5 6 9 11 12 19 47 74 84 91 153];
for s=1:length(N_rng)
this_seed = N_rng(s);
fprintf('Below results are for rng = %d\n', this_seed);
rng(this_seed);
unused_rows=1:N_UE(t);
while ~isempty(unused_rows)
N_UE_rows=ceil(sqrt(randi([numel(unused_rows)])));
if (N_UE_rows+1)==numel(unused_rows);
N_UE_rows=numel(unused_rows);
end
rows=unused_rows(randsample(length(unused_rows),N_UE_rows))
[~,idx]=find(ismember(unused_rows,rows));
unused_rows(idx)=[];
end
end

Could anyone tell me how to implement two different scenario in the same code

Not sure what you're asking. What's wrong with exactly what you posted?

Are you trying to ask how to use if logic to choose between the 2 scenarios?

[Prabha Kumaresan]

The difference between scenario 1 and scenario 2 are

scenario 1 uses the command 
  N_rng=[1 2 23]; N_UE_rows=2; 
and scenario 2 uses 
N_rng=[1 2 5 6 9 11 12 19 47 74 84 91 153];
N_UE_rows=ceil(sqrt(randi([numel(unused_rows)])));
the rest of the command remains the same for both scenario.
I want actually to run the both scenarios using the 
same code,under the condition for scenario 1 uses N_rng=[1 2 23];
N_UE_rows=2;  and scenario 2 uses
N_rng=[1 2 5 6 9 11 12 19 47 74 84 91 153];
N_UE_rows=ceil(sqrt(randi([numel(unused_rows)])));

could you help me to solve it.
