How can i display a vector as a result of a for loop ?

I have this for loop and i want to display the vector of mn. But this program display me only the last value of mn :

for i=0:200:50000
v= -i.*x(:,3);
mn= (max(v)-min(v))./2
end
disp(mn)

ii=0:200:50000;
n = numel(ii);
mn = zeros(n,1);
for jj = 1:n
    v = -ii(jj).*x(:,3); 
    mn(jj) = (max(v)-min(v))./2 ;
end

or without for..end loop

v = x(:,3)*(0:200:50000);
mn = (max(v) - min(v))/2;
