Maybe this is what you're looking for:
julia> bins = Array[[] for i=1:5,j=1:5]
5x5 Array{Array{T,N},2}:
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
julia> push!(bins[1,1], 0)
1-element Array{Any,1}:
0
julia> bins
5x5 Array{Array{T,N},2}:
Any[0] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
Any[] Any[] Any[] Any[] Any[]
