[julia-users] Re: Passing Array{Array{T,N},1} to a function

If you’re trying this out in the REPL, you might have stumbled on the fact that list comprehensions currently aren’t type stable, unless you tell Julia the type of the elements. So instead of Xinput = [Array{Float64}(InnerArrayPts) for r in 1:OuterArrayPts] in your setup, do Xinput =

[julia-users] Re: Passing Array{Array{T,N},1} to a function

Type-inference in the REPL usually doesn’t give you as tight types as you’d like, mainly because it has to give room for what you *might* do in the future. Declaring variables const in the REPL (i.e. in global scope) helps with that, since it gives type-inference some guarantees that the

[julia-users] Re: Passing Array{Array{T,N},1} to a function

Thanks Tomas, works perfectly. I was testing out some code in the REPL... Relatedly and without abusing the thread too much, I wondered if you might be able to help me understand why the setting InnerArrayPts as const created the desired type stable array comprehension? Namely, const
