中文说明：进行逐步线性回归，均值便宜跟踪的示例，IMC-PID是利用内模控制原理来对PID参数进行计算，matlab开发工具箱中的支持向量机，matlab程序运行时导入数据文件作为输入参数，可以实现模式识别领域的数据的分类及回归。
English Description：
Stepwise linear regression, mean cheaper track sample, IMC-PID is by using the internal model control theory is used to calculate the parameters of PID, matlab toolbox development of support vector machine, matlab program is running into data files as input parameters can realize pattern recognition collar in the domain of data classification and regression.
