loopCounter = 1
while true % Infinite loop
  % Insert code here....
  % At bottom of loop, break out of loop if counter = 30
  if loopCounter >= 30
    break;
  end
  % Done with code so now increment loop counter.
  loopCounter  = loopCounter  + 1;
end

However I suggest that it's better to use a "for" loop than an infinite while loop that you have to break out of.

for k = 1:30
  % Your code
end

Or you could have a non-infinite while loop where you test for the loopCounter on the "while" line, as you're normally expected to do. Any reason why you're not doing either of those methods?

i was using it to compare two images that one image is 90% similar to another for this i provided a infinite loop now i m confusing in that two image compared either their pixels match count or histogram so if i choose first one then how it should be written? if i write

for i1=(1:m)

 for j1=(1:n)
                    if image1(i1,j1)==Image2(i1,j1);
                        noisyRSMatchedCount = noisyRSMatchedCount + 1;
                        S(k)=noisyRSMatchedCount/(m*n);

                     end

                end

 end
where s(k)giving matched pixels but problem is that how it will be match 90% , please help me

test=0
while condition & test<=30
  %your code
  test=test+1
end

actually my loop is infinite means while 1 %code end

It's good to avoid infinite loops. You should always have a failsafe in there, like bail out if the number of iterations exceeds some number that you know is abnormally high, which means something went wrong. Otherwise it's possible for your program to hang the computer.
