How to do matrix multiplication?

Hi

I have been studying Matlab for 3 days and ask questions because my problem is not resolved.

I try to multiply the matrices (2X2 3X3...) but A * B or the inverse matrix calculation method should not be used.

(MY THINKING)

A = [1 2 3; 4 5 6; 7 8 9;]
B = [1 2 3; 4 5 6; 7 8 9;]

[m, l] = size(A)
[n, k] = size(B)

 C = zeros(m, k)
 
 for q = 1 : l
     w = 1 : n
         C = (A(:, q) .* B(w, :)
end

What should I do??
