How to generate a matrix/column of data?

Dear scholars,

suppose I have two input data set: a = [1, 2] and b = [11, 12]. Now v as the output will be: v = [f(a(1),b(1)), f(a(1),b(2)); f(a(2),b(1)), f(a(2),b(2))] which is a 2*2 matrix with 4 entities.

Now I need to generate a data set in Excel such that the first column is a, the second column is b and the 3rd column will be v. This matrix will be 4*3. I am not sure how to write such a code for this.

Any ideas?

a = [1, 2]
b = [11, 12]
for i = 1 : length(a)
    for j = 1 : length(b)
        %v = 2*a(i) + b(j)
        v(i,j) = 2*a(i) + b(j)
        MA = [a(i); b(j); v(i,j)] 
        %ab(i,j) = [a(i), b(j)]
    end
end

a  = [1, 2];
b  = [11, 12];
MA = zeros(4, 3);
k  = 0;
for i = 1 : length(a)
    for j = 1 : length(b)
        %v = 2*a(i) + b(j)
        v = 2*a(i) + b(j);
        k = k + 1;
        MA(k, :) = [a(i), b(j), v];
    end
end
