it is in Matlab: Error in ==> MCexam3 at 13 x1(i+1)=x(i)+1/N*random('normal',0,1).^2

Hello I need to evaluate Gaussian integral K=1/(sqrt(2pi) int(-infinity +infinity) x^2 exp(-x^2/2) dx by using K=E[X^2] ∼Kn=1/N sum(x^2) where x follows a normal distribution. So far I have written this: N=1000; for i=1:n x1(i+1)=x(i)+1/N*random('normal',0,1).^2 end x1 but I am...
