for loop and break!!!

for(syntax)-(1st for loop)
   for(syntax)(2nd for loop)
     if(...)
         value
         break
     end
    else(..)
       value
    end
...
....
...

so would the break help in coming out from the first and second for loop , or just second for loop??

You need to set a flag to break out of the outer loop

finishNow = false;
for k1 = 1 : 1000
    for k2 = 1 : 3000
        if someCondition
            finishNow = true;
            break; % out of inner loop.
        end
    end
    if finishNow
        break; % out of outer loop.
    end
end

Break will work for the loop it is in, so the second for loop. It is always good to run an example and check:

for i = 1:10
    for j = 1:2
        if j == 2
           break;
        else
           fprintf('(i,j) = (%d,%d)\n',i,j);
        end
    end
end

As you will see i goes all the way from 1 to 10 but j is always 1. Hope this helps!
