How to store all loop results? how can i solve this problem??

i have the following loop

   for i=1:4
            for j=2:5
                if i<j
               a=i;
               b=j;
              ind=[a,b]
                end
            end
      end

how can i store all results for example: a=

1 2
1 3
1 4
1 5
2 3
2 4
2 5
3 4 
3 5
4 5

Don't do this in a loop: see Jan Simon's much improved solution to this problem.

Answer 1

[Azzi Abdelmalek]

 k=0;
for i=1:4
    for j=2:5
        if i<j
            k=k+1;
            ind(k,1:2)=[i,j]
        end
    end
end

%or

[a,b]=meshgrid(1:4,2:5);
c=[a(:) b(:)];
out=c(diff(c,[],2)>0,:)

What about:

nchoosek(1:5, 2)
