davidleal I rarely use recursion these days, preferring instead to use Lambda helper functions. Occasionally it might be a built-in SCAN or BYROW but, more often, it is a mocked-up version built from REDUCE/VSTACK since it is unusual to require an array of scalars; an array of arrays ...
For example the following python code, uses this idea, but I don't know if it has an easy conversion to Excel (Fast Exponentiation) def fib(n): v1, v2, v3 = 1, 1, 0 # initialise a matrix [[1,1],[1,0]] for rec in bin(n)[3:]: # perform fast exponentiation of the ...
于是按照网上的方法ROS与C++入门教程-搭建开发环境(QT+ros_qtc_plugin)设置快捷方式,并添加修改 Exec 变量一行,中间添加 bash -i -c 即改为 Exec=bash -i -c /home/ubu/Qt5.8.0/Tools/QtCreator/bin/qtcreator ,保存并退出。 然后再次在QTCREATOR中导入工作空间中包的Cmakelists.txt文件后正常。

In general Python will be considerably faster and there are also optimisations for big integers. For example running '%timeit fib(100000)' takes just 5.25ms to return all 20899 digits. In Excel however much of the gains will probably be lost in data transfer so I think lambda solutions are...
onlineusing the following python approach that is really fast: import math def fibo(n):a,b=0,1foriinrange(n):a,b=b,a+breturna print(fibo(74)) But the problem is not the numerical precision of the approximate method. I tested the second formula of my post, which doesn't involve ...
, unless the Python algorithm is also wrong, but it involves just additions too. Thanks, that is the issue, then it is a limitation for any solution starting from 74 Fibonacci numbers because it has 16 digits.The reason the Binet formula doesn't get the correct result is not its own ...
(n=3), etc. so the formula does this backward calculation until the entire recursion is expanded up to the end n=2. On each call of the recursion, only the last row changes from the previous one, adding the next Fibonacci number. It is ensured by the second IF condition until it ...
