How to create a array of arrays. I am trying this. julia> a =[2,3] 2-element Array{Int64,1}: 2 3 julia> b=[] 0-element Array{Any,1} julia> push!(b,a) 1-element Array{Any,1}: [2, 3] julia> empty!(a) 0-element Array{Int64,1} julia> b 1-element Array{Any,1}: Int64[] Here the array b is empty.…

Could you explain what exactly you are expecting? b isn’t empty in your example above: julia> b[1] Int64[] there’s an empty array of integers in b (which you put there and then emptied).

push!(b,deepcopy(a)) or push!(b,copy(a)) would be enough in above example case.
