yes, i know.
i was thinking about something like this...
template <int IsVector>
struct resize_xpr_helper
{
template <typename Derived, typename OtherDerived>
static void run(const Eigen::MatrixBase<Derived>& _this, const
Eigen::MatrixBase<OtherDerived>& other)
{
std::cout << "Matrix assignment" << std::endl;
}
};
template <>
struct resize_xpr_helper<1>
{
template <typename Derived, typename OtherDerived>
static void run(const Eigen::MatrixBase<Derived>& _this, const
Eigen::MatrixBase<Derived>& other)
{
std::cout << "Vector assignment" << std::endl;
}
};
