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.

本程序模拟光的干涉现象：杨氏双缝干涉，劈尖干涉和牛顿环干涉，并计算光的光强分布，另外，附有相应的仿真图(MATLAB for three types of interference of light and calculate the intensity of the and have corresponding figures)
