Reinterpret interleaved real and imaginary numbers to an Abstract Vector

General Usage
1

I am reading interleaved complex data as (abscissa, real, imaginary) numbers in one vector. Elements 1, 4 ,7, … are the abscissa, and elements (2,3), (4,5), … are the (real, imaginary) components of the complex numbers. I would like to have a result of abscissa and ordinate, where the abscissa is a real vector and the ordinate is a complex vector. I am part way there, with the MWE

julia> _data = rand(3*10);

julia> tmp = reshape(reinterpret(Float32, _data), (3, :))';

julia> abscissa = tmp[:, 1];

julia> data = reinterpret(ComplexF32, reshape(tmp[:, 2:3]', (:, 1)));

julia> isa(data, AbstractVector)
false

julia> isa(abscissa, AbstractVector)
true

How can I get Julia to recognize data as an AbstractVector?

The problem is that your data is an AbstractMatrix. What you want to do is

data = reinterpret(ComplexF32, vec(tmp[:, 2:3]'));
