Can you please try to give a more relevant title to your questions in general. Almost every question you ask you just give the same generic title. The question box should be for a short summary of what your question is about. Every question on the board could be titled 'Can you please help with this', but it isn't very useful for people scanning the questions for ones they may be able to contribute to.

Easy enough. Just use setdiff.
A=[2 3;
1 4;
2 4;
3 4];
That is, ...
B = A;
cind = [3 4];
for i = 1:4
B(i,cind(randperm(2))) = setdiff(1:4,B(i,1:2));
end
B is:
B
B =
2 3 4 1
1 4 2 3
2 4 1 3
3 4 1 2
