solution:
v1=[1 4 8 9 3 6 ];
v2=[v1 zeros(1,4)];% change the amount of 0 to increase the probability in this case there are 4
pop=v2(randi(numel(v2),10,4))

without repetition :
v1=[1 4 8 9 3 6 ];
v2=[v1 zeros(1,4)];% change the amount of 0 to increase the probability in this case there are 4
[~, ind] = sort(rand(10,length(v2)),2);
pop=v2(ind(:,1:4))
