What is the best way to convert a larger array to a StaticArray. I have tried the following which works fine for a small array but not for a medium size. using StaticArrays # this works A1 = zeros(UInt16, (3, 4, 5)); @time S1 = SArray{Tuple{3, 4, 5}, UInt16, 3, length(A1)}(A1); # this hangs and d…

From the docs: Note that in the current implementation, working with large StaticArray s puts a lot of stress on the compiler, and becomes slower than Base.Array as the size increases. A very rough rule of thumb is that you should consider using a normal Array for arrays larger than 100 elements.

Thank you for the answer. I will have to refactor some code then. I liked to use the static arrays because I could have the size as part of the type but I will just find another way to handle it.

In case it’s relevant to your use case, it’s okay to have large Arrays of small-ish StaticArrays. For example, zeros(SVector{64, UInt16}, 64, 30) (i.e., a Matrix{<:SVector{64}}) is still within the usable size for SVector. A common example of this pattern is storing large sets of 3D coordinates as a…

Thanks for the answers. For context I am implementing a data reader EUMETlab / Cross-Cutting Tools / MetopNative.jl · GitLab I was autogenerating structs for each record type and many of the fields are fixed sized Arrays. I was using StaticArrays for these fields so the record type contained all ne…

[image] lupemba: Alternatively I will just switch to regular arrays and pipe the array sizes around separately. A regular array has a size attached, just not as part of the type — just call size(A) . You don’t need to pass the array size separately. Why do you want the size to be part of the…

[image] ufechner7: Did you consider to use a SizedArray? API · StaticArrays.jl I have just tried SizedArray. It is easy to construct large SizedArrays but I quick run into compile issues again when I try to use the large SizedArrays. I am sure I can find workaround for many of the things but…
