This statement is wrong in your document.

Iteration is not an attribute of recursion, neither directly or implicitly.
It doesn't guess next result recursively, recursion means calling function by itself.

Recursion is a function which calls itself.
Iteration is simply repetition of a code block.

Here is sample for iteration and recursion.
Usually recursion takes more time to compute.

Fibonacci sequence starts with 0. Your sample is wrong.

0,1,1,2,3,5,8,13,21,34,55

I won't update my code, because it is the correct one.
Fibonacci sequence start with 0 and 1.
If web calculators doesn't include 0, it is their problem.

Fibonacci sequence starts with 0-1, end of debate.
I will try to point out and correct a miscalculation if I could.
I don't care if it is online calculator, mathcad, matlab, smath, etc.
I will always detract when a calculation is wrong and justified.
And I will mock and ridicule it if that mistake defended without reason.

It is time for you to learn when to stop.
Don't post your ridicule ideas and calculations.
And don't humiliate yourself anymore.

You are totally incapable calculating even a very simple thing, AGAIN.
My code is correct, yours is wrong. And this didn't surprised me one bit.

You have mistaken index numbers, since smath vector index start with 1.
Near all other calculators starts index with 0.
fib(0) is 0 for them, fib(1) is 0 for smath.

So yeah, fib(26) is 75025 in SMath.

What is your concept of "hyperfast" and "command line"? Did you do any kind of testing before making such strong statements? Please do some basic research before posting solutions that are not.

Sure it is. This is what SMath developers understand about "command line", which matches the universally accepted concept for that expression ( from https://en.smath.com/view/SMathStudio/faq )

So could you show where the "command line" is in your example?

So, you test your fib against your Julia set ... Do you try to test your fib versus another function that returns Fibonacci numbers?

mod: I've merged the threads, if you have different methods you can list or link them in the first post with the edit button. Unless there is a crystal clear difference in methods and a meaningful title, having multiple threads about the same thing makes really hard to navigate and search topics in the forum.


I agree you should give proper names to things, recursion and iterations are two very different things and they have an estabilished meaning (like "command line", I'm sure this was already discussed in some other thread previously)


To quote myself, this is another simple way to create a Fibonacci sequence in SMath Studio.
