Appending Arrays at the END!

I have three arrays of sizes:

1) A[]=839063*1; (ZEROS)

2) B[]=4393*1; (some values) {example [0.1 0.2 0.3 . . . . ] random values }

3) C[]=191*1; (some values randomized)

Here I need to multiply every element of C[] with EACH element of B[]. like

for i= 1:length(B)

ANS = B(i) * C; { example 0.1 * [1 2 3 4 5 6 7 8 9 . . . . . 191] like this I have to do 4393 times}

END

Then I have to store all these values in array A[] and I have to append these values at the end of the array after each for loop.

Currently I am using the below algorithm to resolve this, and is not working. Can you please tell me a better way to do this????

for i = 1:length(A)
    for j = 1:length(B)
        for k = 1:191
            A(i)=B(j)*C(k);
        end       
    end
    i=i*(191);
end

E.g.,

A = B * C.'; % outer product
A = A(:); % turn into column vector
