I have a mutable type called Data mutable struct Data data_a::Vector{Int64} data_b::Vector{Int64} end I get two vectors that are of type Vector{Float64} from a solution of an ODE and want to construct the type Data field’s being the two vectors. I am using a function to do so some…

[image] LionMod: input.data_a = [state[1] for state in states] This line allocates a new array for the right-hand-side every time you execute it, so it’s hardly surprising that it will allocate. It has nothing to do with whether you store the result in a mutable struct. If you want to avoid…

Reducing memory allocations when storing vectors to fields of a mutable type

General Usage Performance

Vector{SVector{4, Float64}}

And I’m having issues slicing it.
