Detailed Description

template<typename Method, typename Model, typename Observation, typename... Args>
class Emrys::Observed< Method, Model, Observation, Args >

An observation of a measurement model: the observed value, the model, the method that pushes the state through it, and the inputs of the call, as observe() makes it (decisions.md [templated-measurements], [method-per-measurement], [model-policies]).

What a filter's update() takes (see Measurement).

Template Parameters

Method	the transform method, or internal::NoMethod
Model	the model, a MeasurementModel, or a const reference to one that outlives the observation
Observation	the observed value's type, a plain vector, or internal::NoObservation
Args	the call's arguments after the observation: uncertain and sure inputs, the covariance update form, and the repair, each held by value
