how i break nested for loop

hello i have three loops and two conditions and flag and i'm trying to use break statement to break the loop after the second condition true but what i get two variables having same value which is impossible what wrong

temp=0;cov=0;sov=0;
for I=1:30
  for J=1:30
    for N=1:x
      dis=sqrt(((I-test_ary(N,2)).^2)+((J-test_ary(N,1)).^2));
      if(dis<=r)
        if (temp==0)
          cov=cov+1;
          temp=1;
        else
          if(temp==1)
            sov=sov+1;
            temp=0;
            break
          end
        end
      end
    end
  end
end

What is the expected result you're looking for? The first break will only terminate the innermost loop (on N) so the outer loops will still run to completion (which, of course, will start the innermost loop over again each pass). And, of course, since you reset temp in the else clause, the cov accumulator may increment again.

A description of the objective you're trying to achieve might help.

well i have gird of small squares and circles with radius distributed in the area and I'm measuring the distance between each circle and square if the distance less than r the cov increase if two circles have distance less than r with the same square the sov increase and the loop is braked so sov should be smaller than cov not equal

Set a flag:

finishNow = false;  % Call this before the loop to initialize.

Then in the loop:

finishNow = true;

Right before the "ends" for i and j, break if the flag is set:

    if finishNow
        break
    end
  end % of i or j loop

You will need that twice - once for the i loop and once for the j loop.
