专家PID与普通PID的比较，说明专家PID优于普通PID(Compared with common PID, expert PID expert PID is better than the ordinary PID )

本学期研一课程开设了数值方法，由于数值计算是MATLAB一项重要功能，所以结合MATLAB学习数值方法也许是条捷径！为了让大家更好的理解课程内容，更熟练第运用matlab解决数值计算问题，我根据上节课的内容，编写了《拉格朗日多项式逼近》与《牛顿多项式逼近》程序，以抛砖引玉，和大家共同提高！（其中部分程序参考数值方法（MATLAB版）一书） 附件里有m文件和详细的使用方法！ 希望让大家受益！(Lagrange polynomial approximation)
