Using for loop to iterate through matrix of parameters

Hi Folks,

I have produced the following code to calculate G_sl a 3*3 matrix where parameters S_1 and S_2 are 3*1 column vectors

for i=1:size(S_1,1) % 
    k1=S_1(i,1)
    for j=1:3
        k2=S_2(j)

G_sl(i,j) = k1.*(D_mean(1,1).^0.82).*(Fr(1,1) + k2.*Y(1,1).*Fa(1,1));        
    end 
end

Now I wish to calculate the matrix T_sl= G_sl.*mu_sl for all values of G_sl but with an additional parameter n where mu_sl=f(n) How do I script to calculate for all values of G_sl along n a 3*1 column vector

Any information will be greatly appreciated. Regards B
