Namespaces
namespace	apfel
	Namespace for all APFEL++ functions and classes.

Functions
GTMD object initializers
Collection of functions that initialise GtmdObjects structure for the perturbartive evolution and matching currently available.
std::map< int, GtmdObjects >	apfel::InitializeGtmdObjects (Grid const &g, std::vector< double > const &Thresholds, double const &xi, double const &IntEps=1e-5)
	The InitializeGtmdObjects function precomputes the perturbative coefficients required for the evolution and matching of GTMD and store them into a 'GtmdObjects' structure.
GTMD builders
Collection of functions that build a GTMD distributions as Set<Distribution>-valued functions. These functions perform evolution and matching either separately or alltogether.
std::function< Set< Distribution >(double const &, double const &, double const &)>	apfel::BuildGtmds (std::map< int, GtmdObjects > const &GtmdObj, std::function< Set< Distribution >(double const &)> const &CollGPDs, std::function< double(double const &)> const &Alphas, int const &PerturbativeOrder, double const &Ci=1, double const &IntEps=1e-7)
	Function that returns the matched and evolved GTMDs in b-space as functions of the final scale and rapidity.
std::function< Set< Distribution >(double const &)>	apfel::MatchGtmds (std::map< int, GtmdObjects > const &GtmdObj, std::function< Set< Distribution >(double const &)> const &CollGPDs, std::function< double(double const &)> const &Alphas, int const &PerturbativeOrder, double const &Ci=1)
	Function that returns the matched TMD GPDs in b-space.
std::function< Set< Operator >(double const &)>	apfel::MatchingFunctions (std::map< int, GtmdObjects > const &GtmdObj, std::function< double(double const &)> const &Alphas, int const &PerturbativeOrder, double const &Ci=1)
	Function that returns the mathing functions for the GTMDs.
