for loop start from first operation if df=1?

For a=1:20
  Df=0;
  If condition
    Operation(a);
    Condition reset;
    Df=df+1;
  End
  If df==1
    Repeat for loop again how to do it
  End

Arunachalam - I think that you may be able to repeat the above if you use a while loop. Something like

 a = 1;
 while a <= 20
     if condition
         Operation(a);
         % Condition reset;
         a = 1;
     else
         a = a + 1;
     end
 end

Not sure if the above is what you have intended but look how we just use a and not the Df to continue iterating or to restart the loop if some condition is met.

Note that the above code is dangerous as you could get stuck in an infinite loop. You may want to decide how many reset of a to one you should allow before terminating the while loop.
