Trait bayes_estimate::models::KalmanEstimator

pub trait KalmanEstimator<N: SimdRealField, D: Dim> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, D>, {
    fn init(&mut self, state: &KalmanState<N, D>) -> Result<(), &'static str>;
    fn kalman_state(&self) -> Result<KalmanState<N, D>, &'static str>;
}

A Kalman estimator.

The linear Kalman state representation x,X is used to represent the system.

Required methods

fn init(&mut self, state: &KalmanState<N, D>) -> Result<(), &'static str>

Initialise the estimator with a KalmanState.

fn kalman_state(&self) -> Result<KalmanState<N, D>, &'static str>

The estimator’s estimate of the system’s KalmanState.

fn init(&mut self, state: &KalmanState<N, D>) -> Result<(), &'static str>

Initialise the UDState with a KalmanState.

The covariance matrix X is factorised into a U.d.U’ as a UD matrix.

fn kalman_state(&self) -> Result<KalmanState<N, D>, &'static str>

Derive the KalmanState from the UDState.

The covariance matrix X is recomposed from U.d.U’ in the UD matrix.
