% W,H values is for example .. They can be with any dimension but always the number of rows of H is equal to the number of columns of W and the matrices are not squared .
% when i=1 ... Alfa_1 is the multiplication between the first row of H and the first column of W and Alfa _2 is the sum of multiplying the other rows and columns except for the multiplication between the first row of H and the first column of W
% when i=2 ... Alfa_1 is the between the second row of H and the second column of W and Alfa _2 is the sum of multiplying the other rows and columns except for the multiplication between the second row of H and the second column of W.
And goes like this to the end of iterations, also (k) is equal to the number of rows of H and the number of columns of W
H=[1 2 2 1 ; 3 1 1 2;1 3 2 4]
W=[4 1 2 ;1 3 2 ;2 1 3;2 1 4]
for i=1:k
Alfa_1 = H(i,:)*W(:,i);
Alfa_2 = ........
end

I consider you want to find Alfa_1 and Alfa_2 at each iteration, so you can modify the above code as,
H=[1 2 2 1 ; 3 1 1 2;1 3 2 4];
W=[4 1 2 ;1 3 2 ;2 1 3;2 1 4];
[k,l]=size(H);
for i=1:k
Alfa_1(i) = H(i,:)*W(:,i);
Alfa_2(i) = 0;
for j=1:k
Alfa_2(i) = Alfa_2(i) + H(i,:)*W(:,j);
end
Alfa_2(i) = Alfa_2(i) - Alfa_1(i);
end
Alfa_1 and Alfa_2 are the arrays which contains value of each iteration.
