中文说明：MATLAB实现简单地卡尔曼滤波算法，首先生成运动轨迹，然后添加高斯噪声，再通过卡尔曼滤波算法进行滤波处理，最后输出得到运动轨迹。该算法简单，适合于对卡尔曼滤波的初步学习，很有帮助！
English Description：
MATLAB implementation simply Kalman filter algorithm, the first generation trajectory, then add Gaussian noise, and then filtered through a Kalman filter algorithm, the final output obtained trajectory. The algorithm is simple and suitable for the preliminary study of the Kalman filter, and helpful!
