Hi all!
I’m trying to create an empty vector that will be pushed with values inside a for loop. I tried the following:
```julia
δ_arr = Vector{Any}[]
ϵ₀_arr = Vector{Any}[]
M_arr = range(0.01e6, 0.9e6, 10)
for i in 1:length(M_arr)
ep, si, t_b, lag, amp = strain_ampli_f(𝑓, M_arr[i], B_g)
push!(ϵ₀_arr, amp)
push!(δ_arr, lag)
end
```
But for some reason I’m getting:
```julia
MethodError: Cannot `convert` an object of type Float64 to an object of type Vector{Any}
```
On the push command. Not sure what I’m missing. Appreciate any help!!
Thank you!

You want `Any[]` (or just `[]`). `Vector{Any}[]` is a `Vector` that stores `Vector{Any}`s.

Perfect!! That was lightning fast and enlightening 🙂
