% Simulation parameters dt = 1; % time step (seconds) T = 50; % total time steps

x = [position; velocity] position_new = position_old + velocity_old * dt velocity_new = velocity_old Full MATLAB Code % Kalman Filter for 1D Motion (Position + Velocity) clear; clc; dt = 0.1; % time step T = 100; % number of steps true_vel = 5; % m/s true_pos = 0; kalman filter for beginners with matlab examples download

% --- Update --- x_est = x_pred + K * (z - H * x_pred); P_est = (eye(2) - K * H) * P_pred; % Simulation parameters dt = 1; % time

% Initial state [position; velocity] x_est = [0; 0]; P_est = [10 0; 0 10]; % Simulation parameters dt = 1

% --- Prediction step --- % For constant temperature, prediction = previous estimate x_pred = x_est; P_pred = P_est + process_noise_std^2;

% Initial guess x_est = 20; % initial estimate (wrong on purpose) P_est = 5; % initial uncertainty (high)

% Noise parameters process_noise_pos = 0.1; process_noise_vel = 0.1; meas_noise_pos = 3; % GPS-like noise
