KALMAN FILTER FOR BEGINNERS - MATLAB EXAMPLES =============================================== Requirements: MATLAB R2018b or newer No toolboxes required (uses only core MATLAB)

Imagine you are in a car trying to measure your speed. Your speedometer is good, but it's a bit noisy (it fluctuates when you hit bumps). You also have a GPS that measures your position, but it updates slowly and is sometimes inaccurate. % Initial state [position
% Basic 1D Kalman Filter: Estimating Position from Noisy Measurements dt = 1; % Time step A = [1 dt; 0 1]; % State transition: pos_new = pos + vel*dt H = [1 0]; % Measurement: we only measure position Q = [0.1 0; 0 0.1]; % Process noise covariance R = 5; % Measurement noise covariance (noisy sensor) x = [0; 10]; % Initial state [position; velocity] P = eye(2); % Initial uncertainty for k = 1:50 % 1. Predict x = A * x; P = A * P * A' + Q; % 2. Update (assuming 'z' is your new noisy measurement) z = (10 * k) + randn*sqrt(R); % Simulated noisy measurement K = P * H' / (H * P * H' + R); x = x + K * (z - H * x); P = (eye(2) - K * H) * P; end Use code with caution.
