Hi Dev team,
I am digging around in the stan math library to use in some software that I work on. The program does non-linear optimisation and already has multiple autodiff libraries e.g. adolc (https://projects.coin-or.org/ADOL-C).
We use boost’s lexical cast to assign values to objects (I guess in the case for Stan that is var.vi_->val_) from files. I see in (https://github.com/stan-dev/math/blob/develop/stan/math/rev/core/var.hpp) you have overloaded the ostream << operator, I was wondering if there is a reason why you haven’t overloaded the istream >> operator? would this be easy? I am not having much luck.
My C++ isn’t great but I am hoping to get Stan into this software for my PhD so any advice would be greatly appreciated.
