MATLAB: Vector composition

vectors

If I have several vectors such as u=[x1 x2], v=[x3 x4], w=[x5 x6] is there anyway I can combine them to get g=[x1 x2 x3 x4 x5 x6] ?

nevermind, got it figure out! g=[u v w];

1.2 - Try to use finverse

1.3 - Use loops to solve

N=3; % number of terms
v=sqrt(2);
for i=1:N-1
v=sqrt(2+v);
end
v

To find convergence use a very large value of N

Perhaps I'm misunderstanding but if

 x = [1.0000         0
      0.5000    1.0000
      0.5000    1.5000
           0   -1.0000
     -1.0000    1.0000
      0.5000   -1.0000];

which is a 6x2 array, then wouldn't

 x*x'

be the desired 6x6 array?
