Lambda Example: Generate Fibonacci series In this post, I would like to explain how I have used Lambda to create a function to generate a Fibonacci series array. This example can also be used to understand how to create an array where th...Show...
and we'd like the power series to converge. We know the Fibonacci numbers grow like ϕn and that geometric series Σnan converge if |a|<1, so we know that if |x|<1/ϕ≃0.618 then the power series converges.
I did some testing performance and the result in terms of performance are the same as expected. It brought my attention that when I compareboth solutions around 160th Fibonacci number the result differs from the Python algorithm I share before. what is curios is that the difference comes from...
This is used to specify an unused variable in Python, I don't know if this convention is more widespread. See Fibonacci code further down this link https://realpython.com/python-itertools/#recurrence-relations underscore is used both within accumulate (equivalent to SCAN) and within the for ...
Now it may be possible to do some of these things in Python but that is some way off for me! Playing with the concept a bit more, it could be worth defining a generalised SCAN function that applies to both types of setup. For Fibonacci sequence, ...

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...
