利用龙格库塔法解布洛赫方程 有较为详细的注释 简单易懂(Solving Bloch Equation by Runge-Kutta Method)

When I first studied Kalman filtering, I saw many advanced signal processing submissions here at the MATLAB Central File exchange, but I didn t see a heavily commented, basic Kalman filter present to allow someone new to Kalman filters to learn about creating them. So, a year later, I ve written a very simple, heavily commented discrete filter.
