       if(y+1 <= length(B))
         if(sum(ismember(closed(:,1:2),[x,y+1],'rows'))== 0)  
           cost = hMap(x,y)+ B(x,y+1); 
           if(cost< hMap(x,y+1))
             hMap(x,y+1) = cost;
             open = [open;x,y+1,cost]; 
           end
         end
       end

There are no loops in the code you've shown.

The open = [open;x,y+1,cost]; suggests it is in a loop, but we do not have information about which variable is being iterated over; we also do not have information about what the purpose of the code is.
