Can anybody help on this FOR loops

I do not really understand what exactly is wrong here.

I want to have the following variables give seperate results for each n.

Can you help me correct this?

for n = 1:N
   Ln(n)=V(1:N,n)'*M*l
   Mn(n)=V(1:N,n)'*M*V(1:N,n)
   Gamma_n(n)=Ln/Mn
   Mn_star(n)=Ln^2/Mn
   fn_st(n)=Gamma_n.*M*V(1:N,n)
end

Does all the variables return a scalar in each iteration?

[Murad Nuri]

It does. But after each step of n, the previous value for the variable vanishes, this is not i want to have. I want for n=1 to have Ln(1), etc, for n=2 Ln(2), etc...

[Ln, Mn, Gamma_n, Mn_star, fn_st] = zeros(N,1);
for n = 1:N
   Ln(n)=V(1:N,n)'*M*l;
   Mn(n)=V(1:N,n)'*M*V(1:N,n);
   Gamma_n(n)=Ln(n)/Mn;
   Mn_star(n)=Ln(n)^2/Mn;
   fn_st(n)=Gamma_n(n).*M*V(1:N,n);
end
