By "casting" do you mean a zero-copy way of sharing the same internal
buffer? There is no easy way to do that, and seems very unsafe.

If copying is ok, then the simplest way is

    std::copy_n (matrix.data (), matrix.numel (), vector.begin ());

    std::copy_n (vector.begin (), vector.size (), matrix.data ());

Hope that helps,
