Why does my function give no outputs?

function [A]=AccGold()
n = 4;
    while Gold(n)-Gold(n-1) > 0.00000001
       n = n+1;
       A = Gold(n)
    end  
end

I want to find the first value of Gold(n)-Gold(n-1) such that it is < 0.0000001

If the condition is immediately false you never assign to A.

I want the loop to run until n is such that Gold(n)-Gold(n-1)<0.0000001, and then I want the value of Gold(n) at this n. Is there an easy way to change my function to do this?

[Walter Roberson]

Initialize A=Gold(n)
