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?

There is no quick way. You have an error at some unknown point in your code. You need to re-examine your code and debug it.
NaN would be produced if you had 0/0 or inf*0
I suggest that at the command prompt you type
dbstop if naninf
and run again. It will stop at the point the first NaN or Infinity is produced.
