Right, hcat(a…) does that (up to a transpose since julia stores things in
column major order ).
julia> a = Array(Array, 0)
0-element Array{Array{T,N},1}
julia> push!(a, [1, 2])
1-element Array{Array{T,N},1}:
[1,2]
julia> push!(a, [3, 4])
2-element Array{Array{T,N},1}:
[1,2]
[3,4]
julia> b = hcat(a...)
2x2 Array{Int64,2}:
1 3
2 4
julia> b[:, 2]
2-element Array{Int64,1}:
3
4

I mean, is there a function that allows me to take in a and return a matrix?
