I am looking for examples: show me some real computational power in seven or fewer lines of Julia that read clearly. It is ok to be using other packages, though no more than four (and it is ok to use fewer). Each example is intended to make a compelling case for Julia to skilled practitioners of w…

:grin: Many thanks. Best wishes, Niall.

@Niall @greatpet @Henrique_Becker I feel like nest() & nestlist() are super-useful functions. They are standard in other packages as Mathematica… Could there be any value in having something like nest() & nestlist() added to Base?

In Julia v1.8 we’ll have the possibility of type-annotating global variables, to promise their type won’t change: julia> x::Float64 = 3.14 3.14 julia> x = 2.71 2.71 julia> x = "hello world" ERROR: MethodError: Cannot `convert` an object of type String to an object of type Float64 Wouldn’t it be …

Very nice! You can use two of your remaining three lines for using Plots plotF(x, N) = plot(hcat(first(iterated(F, x), N+1)[begin+1:end]); seriestype=:scatter) to see the convergence. [convergence]

Nice idea. I tried, as an exercise, to make a graph myself. Maybe @rafael.guerra can make it dynamic. PS but couldn’t plot work with iterators and thus build the graph dynamically? using IterTools, Statistics, Plots F(x)=[mean(x),prod(x)^(1/length(x)), median(x)] F1nx(x,n)= last(firstrest(t…

@rocco_sprmnt21 , as you asked, I felt obliged. See a simple code below, FWIW: using IterTools, Statistics, Plots; gr(size=(800,600), dpi=600) F(x) = [mean(x),prod(x)^(1/length(x)), median(x)] F1nx(x,n) = last(firstrest(takestrict(iterated(F,x),n))) function plotF(x,N) plot((1:3)', [NaN, NaN, …

using IterTools
using Statistics
F(x)=[mean(x),prod(x)^(1/length(x)), median(x)]
Fnx(x,n)=nth(iterated(F,x),n)

Is there a way to repeatedly call a function
