Rhis is an article concerning vectorisation in Julia.  
I think your loop should vectorise well - each i is independent.  
[https://juliacomputing.com/blog/2017/09/27/auto-vectorization-in-julia.html](https://juliacomputing.com/blog/2017/09/27/auto-vectorization-in-julia.html)

You also consider the type of the array which you use. Is N a fixed size?

> The type of a regular Julia Array only includes the number of dimensions, not the size: julia\> typeof(Array{Int64}(3)) Array{Int64,1} julia\> typeof(Array{Int64}(10)) Array{Int64,1} julia\> typeof(Array{Int64}(1000000)) Array{Int64,1} so the difference between a StaticArray and an Array is exactly what the docs here say: [https://github.com/JuliaArrays/StaticArrays.jl](https://github.com/JuliaArrays/StaticArrays.jl) , namely that the size of a StaticArray is actually part of the type: julia\> typeof(SVector(0, 0)) StaticArrays.SArray{Tuple{2}…
