Classes

	Angle descriptions for the combineBoundGaussianMixture function. More...
struct	Acts::detail::CyclicRadiusAngle< Idx >
struct	Acts::detail::AngleDescription< type_t >
	A compile time map to provide angle descriptions for different surfaces. More...

Namespaces
namespace	Acts
	Acts includes to create all necessary definitions.
namespace	Acts::detail
	These functions perform the transport of a covariance matrix using given Jacobians. The required data is provided by the stepper object with some additional data. Since this is a purely algebraic problem the calculations are identical for StraightLineStepper and EigenStepper. As a consequence the methods can be located in a separate file.

Enumerations
enum	Acts::MixtureReductionMethod

Functions
template<typename Callable >
auto	Acts::detail::angleDescriptionSwitch (const Surface &surface, Callable &&callable)
template<int D, typename components_t , typename projector_t , typename angle_desc_t >
auto	Acts::detail::gaussianMixtureCov (const components_t components, const ActsVector< D > &mean, double sumOfWeights, projector_t &&projector, const angle_desc_t &angleDesc)
template<typename components_t , typename projector_t = Identity, typename angle_desc_t = AngleDescription<Surface::Plane>::Desc>
auto	Acts::detail::gaussianMixtureMeanCov (const components_t components, projector_t &&projector=projector_t{}, const angle_desc_t &angleDesc=angle_desc_t{})
	Combine multiple components into one representative track state object. The function takes iterators to allow for arbitrary ranges to be combined. The dimension of the vectors is infeared from the inputs.
template<typename mixture_t , typename projector_t = Acts::Identity>
auto	Acts::reduceGaussianMixture (const mixture_t &mixture, const Surface &surface, MixtureReductionMethod method, projector_t &&projector=projector_t{})
