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
