My strange nested for loops

Hello buddies,
I've gotten myself into a bit problematic nested if loop. And I have hard time thinking this out.
Imagine 3 for loops and 1 if.
if true
for Ll=LL:LH
    for Lh=LL:LH
        if  Ll<=Lh
        for i=Ll:Lh 
end
My settings is LL and LH e.g: LL=1 and LH =3 (Both can be higher and with higher range). Then I would like i to make all combinations as long Ll<=Lh - and just one time!
in this example I get the following for i's:
if true
Ll=1 and Lh=1   ->  for i=1:1
Ll=1 and Lh=2   ->  for i=1:2  *   repeats the 1:1 as above
Ll=1 and Lh=3   ->  for i=1:3  *   repeats the 1:1 as above
Ll=2 and Lh=2   ->  for i=2:2   
Ll=2 and Lh=3   ->  for i=2:3  *   repeats the 2:2 as above
Ll=3 and Lh=3   ->  for i=3:3
end
The problem is that the above  for-i-loops repeat them self a couple of times (the one marked with stars).
Hope to hear from someone! Have a good day, -best

      In order for i to make all combinations as long Ll<=Lh, the third for loop is not required.
Try this:
 for Ll=LL:LH
    for Lh=LL:LH
        if  Ll<=Lh
                fprintf('%d %d\n',Ll,Lh);
        end
    end      
end
