If there are 4 users in the system say(1,2,3,4) and i want to form pair such that each pairs should contain 2 users under the condition user present in one pair should not be present in other pair.with respect to 4 users 2 pairs can be formed with 3 different combinations combination1 - (12),(34) combination2 - (13),(24) combination3 - (14),(23)

I have written the code

unused_rows=1:4
while ~isempty(unused_rows)  
N_UE_rows=2;   
rows=unused_rows(randsample(length(unused_rows),N_UE_rows))
[~,idx]=find(ismember(unused_rows,rows))
unused_rows(idx)=[]
end

If i run the code i can get the result for only one combination but how to get the result for the other two combinations.

could anyone help me to solve this issue
