boost-accumulators

问题 Having not found a 'boost' way of resetting an accumulator in C++, I came across a piece of code that seems to reset a boost accumulator. But don't understand how it is achieving it. The code is as below - #include <iostream> #include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics/stats.hpp> #include <boost/accumulators/statistics/mean.hpp> using namespace boost::accumulators; template< typename DEFAULT_INITIALIZABLE > inline void clear( DEFAULT_INITIALIZABLE&

问题 I am having some problems combining Eigen::VectorXd types with the Boost accumulator library: #include <iostream> #include <Eigen/Core> #include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics/stats.hpp> #include <boost/accumulators/statistics/mean.hpp> using namespace boost::accumulators; using namespace Eigen; int main() { Vector2f a(1.0, 2.0), b(3.0, 10.0); accumulator_set<Vector2f, stats<tag::mean> > acc(Vector2f::Zero()); acc(a); acc(b); std::cout << mean

问题 I want to use a boost::accumulator for defining a moving average of my custom class: boost::accumulators::accumulator_set<MySample, boost::accumulators::stats<boost::accumulators::tag::rolling_mean> > My problem is that my sample is a user defined class (vector implementation of another library). I've seen in this post that's possible to define accumulators for std::vectors, but it does not specify which operator must be overloaded because it overloads them with boost/accumulators/numeric
