[ANN] Fatou.jl : Easily share Julia fractals

Out of curiosity, what was the timing before type parameters, for running that code?

In this post, I had a comparison of n=1500 grid, which took 19 seconds before, while only taking 0.17 seconds in the new version with the parametric types.

Structs and parametric constructors

Well, I am a german speaker also, but probably not everyone on this website is. What you could do is write a single while loop, which has the if statement inside the condition, as I have done in my code shown above. Amazingly, with this improvement the difference is enormous for larger n, with old definition julia> newton(:(z^3-1);n=1500)|>fatou; 19.215167 seconds (65.07 M allocations: 1.817 GiB, 7.66% gc time) However, with new definition julia> newton(:(z^3-1);n=1500)|>fatou; 0.175065…

It’s probably due to assigning the Fatou.Define object to parallel threads, because the iteration function depends on two Bool values in that object and also functions in it, which might become unnecessary now due to the information provided by the parametric type. Now, only the complex number is variable.
