斐波那契数列(Fibonacci sequence),又称黄金分割数列、因意大利数学家列昂纳多·斐波那契(Leonardoda Fibonacci)以兔子繁殖为例子而引入,指的是这样一个数列:1、1、2、3、5、8、13、21、34。。。这个数列从第3项开始,每一项都等于前两项之和。 根据以上定义,用python定义一个函数,用于计算斐波那契数列中第n项的数字...

In column, A you have the final result, but the recursion goes back up to the n=2 (column D), so you should read it from column D (n=2) to column C (n=3), etc. so the formula does this backward calculation until the entire recursion is expanded up to the end n=2. On eac...
REDUCE is a function one can abuse to augment things (via VSTACK). How lovely counter-intuitive. In theory, SCAN might be expected to support such a use, but it won't have any of it. Will try to apply this to my own HRECURSE (to perhaps get rid of the (unnecessary) recursion)....

Recursion is perhaps the most obvious solution, and one which you have likely already seen a billion times, most likely as the go-to example of recursion. But here it is again, for the sake of comparison later. We can do it in one line in Python: fib = lambda n: fib(n - 1) +...
Hi Peter, I must admit I had replied from my phone to the previous message without examining your file - looking more closely I see your formulas are running horizontally across the table. As Sergei implies, I think you'd need to transpose the Fibonacci setup and augment the MAP parameters...
, unless the Python algorithm is also wrong, but it involves just additions too. not a problem at all, indeed your approach is very interesting too. I realized that the problem of numerical precision is affecting not just the Binet formula, but also the initial approach I provided in my ...
