There are many ways to do that:
1) place a test inside the loop to execute instructions based upon some
conditional:
    for k=1:10
      if k < 3 || k > 4 
        k
     endif
    endfor
2) use the "continue" or "break" to skip parts of the loop
    for k=1:10
      if k> 2 && k < 5 continue; endif
      k
    endfor
3) vectorise the loop
    myloop =  (1:10); myloop(myloop > 2 & myloop < 5) = []; %# remove some
elems
    for k = myloop,
      k
    endfor
