Matlab loop not working properly -

largest = 0; num = 0; temp = 0; num_flip = 0;  x = 100 : 999      y = x : 999        num = x*y;        temp = num2str(num);        num_flip = str2double(fliplr(temp));         if num/num_flip == 1           largest = num;           1 = x;           2 = y;        end    end    end 

i'm trying find largest palindrome made product of 2 3-digit numbers reason loop stops @ x = 924 , y = 962 know that's not answer. code works fine 2-digit numbers(10 : 99) though.

you not testing if largest largest code. go through loops possible smaller palindrome detected after larger one, , reassigning largest it.

try added test whether new palindrome larger current largest:

largest = 0; num = 0; temp = 0; num_flip = 0;  x = 100 : 999     y = x : 999        num = x*y;        temp = num2str(num);        num_flip = str2double(fliplr(temp));         if ((num/num_flip) == 1) && (num > largest)           largest = num;        end  end end 

i removed these assignments

one = x; 2 = y;  

because it's not clear question. add them if needed reason not shown.
