Struct KalmanFilter1D 

pub struct KalmanFilter1D {
    pub x: f32,
    pub p: f32,
    pub q: f32,
    pub r: f32,
}

Scalar (1D) Kalman filter for single-variable sensor smoothing and estimation.

Fields

x: f32

Estimated state

p: f32

Estimation error covariance

q: f32

Process noise covariance

r: f32

Measurement noise covariance

Implementations

impl KalmanFilter1D

pub fn new(x0: f32, p0: f32, q: f32, r: f32) -> Self

Initialises a 1D Kalman filter with initial estimate x0, initial covariance p0, process noise q, and measurement noise r.

pub fn predict(&mut self, u: f32)

Prediction step incorporating process input u (optional control input).

pub fn update(&mut self, z: f32) -> f32

Measurement update step with new sensor reading z. Returns updated state estimate.
