If you have deep learning toolbox
A = [1 2 3];
B = [5 6 7];
M = fliplr(combvec(B, A).');
Result
>> M
M =
1 5
1 6
1 7
2 5
2 6
2 7
3 5
3 6
3 7
or without toolbox
A = [1 2 3];
B = [5 6 7];
[a, b] = meshgrid(A, B);
M = [a(:) b(:)];

You can use the functions repmat and repelem.
if true
A = [1 2 3];
B = [5 6 7];
A = repelem(A,1,length(A));
B = repmat(B,1,length(B));
M = [A;B]';
end
