Defining intitial value for parameters as a vector for each parameter

[Mehdilotfi7]

Hi, and thank you for your excellent package. I am trying to estimate the parameters of an age structure model, so in this kind of model, elements of the initial value for the parameters are vectors; when I define the initial condition as above, I receive this error: How can I solve it? Is there any method for that? MethodError: no method matching (Vector)(::Matrix{Float64}) Closest candidates are: (Array{T, N} where T)(::AbstractArray{S, N}) where {S, N} at ~/.local/julia-1.7.3/share/julia/base/boot.jl:479 (Vector)() at ~/.local/julia-1.7.3/share/julia/base/baseext.jl:38 (Vector)(::DataFrames.GroupKey) at ~/.julia/packages/DataFrames/zqFGs/src/groupeddataframe/groupeddataframe.jl:617

How do you define your initial population? From the error it looks like your population is defined as matrix, you may want to convert it into vector of vectors.
