Hi Sokol,
Yes, that explains it. I ended up implementing the solution that you and
Dirk identified, which is to simply convert the vector 'v' to an armadillo
vector for the purpose of copying from it.
Thanks for the help!

Hi Dirk,
I take your point. Given that the conversion is essentially free, temporary
conversion makes the most sense.
Thank you again!

Hi Dirk,
Thanks for the quick response. In the broader project, the vector being
copied from is an Rcpp::NumericVector that contatenates vectorized versions
of a number of other objects that are integrated numerically using the
boost odeint solvers. I couldn't quite get the numerical integrators t
