The Kalman filter is a mathematical algorithm used to estimate the state of a system from noisy measurements. It is widely used in various fields such as navigation, control systems, and signal processing. The Kalman filter is a powerful tool for estimating the state of a system, but it can be challenging to understand and implement, especially for beginners. In this report, we will provide an overview of the Kalman filter, its basic principles, and MATLAB examples to help beginners understand and implement the algorithm.

% Define the system matrices A = [1 1; 0 1]; B = [0.5; 1]; H = [1 0]; Q = [0.001 0; 0 0.001]; R = 0.1;
