Visual C ++ Odeint集成
我试图在Visual C ++中使用integrate_const ，作为带有重载operator()的类的一部分。 为什么编译器无法专门化模板？
size_t steps = boost::numeric::odeint::integrate_const(stepper, *this, x, tbegin, tfinal, dt, obs);
我收到了IntelliSense和编译错误：
没有重载函数“boost :: numeric :: odeint :: integrate_const”的实例匹配参数列表c： Users ... src duffing.cpp 81
此外，它给出了消息：
错误C2893未能特化函数模板'size_t boost :: numeric :: odeint :: integrate_const（步进器，系统，常量状态＆，时间，时间，时间，观察者）'aimsexamples C： Users ... src duffing .cpp 81
