Emrys::GaussianMixtureHistory< Space_, Scalar_, Allocator_ >::Step Class Reference

One recorded prediction and its smoothed mixture, built from the history's allocator. More...

#include <EmrysFilter/Smoothers/GaussianMixtureHistory.h>

Public Types
using	allocator_type = Allocator_
	the allocator its joint and mixture come from
using	GainType = typename GaussianParams<Space_, Scalar_>::MatrixType
	One component's Rauch-Tung-Striebel gain.
using	GainAllocator = internal::ReBound<Allocator_, GainType>
	The allocator of the gains.

Public Member Functions
	Step (JointType const &recorded, Allocator_ const &allocator={})
	A copy of recorded in storage from allocator, with the filtered mixture as its smoothed one until smooth() runs.
	Step (JointType &&recorded, Allocator_ const &allocator={})
	recorded moved into storage from allocator, with the filtered mixture as its smoothed one until smooth() runs.
	Step (Step const &other, Allocator_ const &allocator)
	Copies other into storage from allocator.
	Step (Step &&other, Allocator_ const &allocator)
	Moves other into storage from allocator, taking its storage when the allocators are equal.
	Step (Step const &)=default
	copies the joint and the smoothed mixture
	Step (Step &&)=default
	moves the joint and the smoothed mixture
Step &	operator= (Step const &)=default
	Copies into this step's storage.
Step &	operator= (Step &&)=default
	Takes the other step's storage, as the members' do.
void	resetSmoothed ()
	Replaces the smoothed mixture with the filtered one: the joint's weights and each component's filtered Gaussian.
void	computeGains ()
	Computes each component's gain from its joint (internal::rtsGain()), once per recording.

Public Attributes
JointType	joint
	the prediction as predictJoint() recorded it
SmoothedType	smoothed
	\( p(x_k \mid z_{1:N}) \), a component per component of the joint, as of the last smooth(); the filtered mixture until then
internal::Buffer< GainType, Allocator_ >	gains
	Each component's Rauch-Tung-Striebel gain, made once when the joint is recorded.
