A=[1 2;4 3] %edited
[m,n]=size(A);
result=cell(1,m);
for i = 1:m
result{i}=[A(1,i).*(A)];
end
result=horzcat(result{:})

Not clear what you want but KRON might be what you are looking for
>> A=[1 2; 4 3]
A =
1 2
4 3
>> kron(A,A)
ans =
1 2 2 4
4 3 8 6
4 8 3 6
16 12 12 9
>> kron(A,[1,2])
ans =
1 2 2 4
4 8 3 6
>> kron(A,[1;2])
ans =
1 2
2 4
4 3
8 6
>> kron([1,2],A)
ans =
1 2 2 4
4 3 8 6
>> kron([1;2],A)
ans =
1 2
4 3
2 4
8 6
