中文说明：卡尔曼滤波代码，一维数据滤波。参数需要自己调到，慢慢来吧，需要自己再建一个.m文件调用，给他们赋值，之后调用，可以用MATLAB自带的xlxread（）读取数据，比较简单的的滤波代码，仅供参考，一般用于数据预处理去噪，和均值滤波效果差不多
English Description：
Kalman filter code, one-dimensional data filtering. Parameters need to be transferred to them, slowly, you need to build another.M file call, assign them value, then call, you can use MATLAB xlxread () to read data, relatively simple filtering code, for reference only, generally used for data preprocessing, denoising, and mean filtering effect is almost the same.
