How to generate matlab workspace variable in matrix format

I have a matlab code that generate different combination between matrix. I am using it as part of a bigger script. Below is just example

A=[1,2,3,4];
B=[1,2,3,4];

for i=1:size(A,2);
    for j=1:size(B,2);           
C=[A(1,i),B(1,j)]

    end
end

It will generate different possible combination between Matrix A and Matrix B as below.

C =

 1     1

C =

 1     2

C =

 1     3

C =

 1     4

C =

 2     1

C =

 2     2

C =

 2     3

C =

 2     4

C =

 3     1

C =

 3     2

C =

 3     3

C =

 3     4

C =

 4     1

C =

 4     2

C =

 4     3

C =

 4     4

But in my workspace variable, C shows only (4,4) which is the last answer. How to do if I want to get all C answer in one big matrix as 

1 1 
1 2
1 3
1 4
2 1
2 2
2 3
2 4 
.... etc (which will be 16,2 matirx). Thanks.

You can concatenate the matrix by using C=[C;A(1,i),B(1,j)];. Of course,that requires C to be initialized as an empty matrix. In your case, the final code is:

A=[1,2,3,4];
B=[1,2,3,4];
C=[];

for i=1:size(A,2);
    for j=1:size(B,2);           
     C=[C;A(1,i),B(1,j)];
    end
end
