The Kalman filter is a mathematical algorithm used to estimate the state of a system from noisy measurements. It's a powerful tool for a wide range of applications, including navigation, control systems, and signal processing. In this guide, we'll introduce the basics of the Kalman filter and provide MATLAB examples to help you get started. % Initialize the state and covariance x0 =

Let's consider an example where we want to estimate the position and velocity of an object from noisy measurements of its position and velocity.
% Define the system parameters dt = 0.1; % time step A = [1 dt; 0 1]; % transition model H = [1 0]; % measurement model Q = [0.01 0; 0 0.01]; % process noise R = [0.1]; % measurement noise
% Generate some measurements t = 0:dt:10; x_true = sin(t); y = x_true + 0.1*randn(size(t));
