How do I create (and retain) the elements of vectors using for loop?

I want a function file to output two vectors 'pi_estimate' and 'error' of length 'n' each. I'm initializing the vectors with zeros(1,n) and then using a for loop to create the elements of the vectors, but, in the output, I get only the last elements (all other elements are zero). It seems like all the elements other than the last ones aren't retained while carrying out the for loop. Any help is much appreciated. Here's my code:
function [pi_estimate,error]=pi_estimate(n)
%function [pi_estimate,error]=pi_estimate(n)
%This m-file estimates the value of pi in 'n' iterations
a=1;
b=6;
pi_estimate=zeros(1,n);
error=zeros(1,n);
for i=1:n
b=2*b;
a=(2-(4-a^2)^0.5)^0.5;
L=a*b/2;
u=L/(1-a^2/2)^0.5;
pi_estimate(1,n)=(u+L)/2;
error(1,n)=(u-L)/2;
end
end

You have used n instead of i
pi_estimate(1,i)=(u+L)/2;
error(1,i)=(u-L)/2;
