Also, it seems like what you really want is a conatiner for 2 Vectors. In
julia, Vector{T} is a typealias for Array{T,1}... The things in brackets
are the parameters. For Array{T,N}, the first parameter T is the type
inside the array, and N is the array dimension. So maybe you want:
type DataArray
Y::Vector{Complex128}
w::Vector{Float64}
end
