Help!! I'm writing a code for Gauss Elimination Method, but my array of returned x(i) gives the result:

ans =

   NaN
   NaN
   NaN
   NaN
   NaN

I looked online but still can't find any useful solutions, does someone know any quick way of fixing this?

I used this person's code: http://www.youtube.com/watch?v=-W_XzoBwiSY to try to find the solution for a = [1 1 -1 1 -1 2; 2 2 1 -1 1 4; 3 1 -3 -2 3 8; 4 1 -1 4 -5 16; 16 -1 1 -1 -1 32] with n = 5
