So, this is a Matlab function to find greatest common divisor with the Euclidean algorithm. Apparently, I missing two rows (where there's percent signs instead) in the end of the function but I can't figure those two rows out. Any help?


Code:
function [ d ] = GCD_Euclidean( x,y )
if ((x <= 0) || (y <= 0) || (x == y))
    d = 0;
    disp(['...']);
    return
end
if (y > x)                          
   a = y;
   b = x;
else
   a = x;
   b = y; 
end                                 
while (b > 0),                      
    d = b;                          
    r = mod(a,b);                   
    q = (a - r) / b;                
    disp(['a = ', num2str(a), ',  b = ', num2str(b) ]); 
    %
    % 
end 

end
