1、掌握用MATLAB计算拉格朗日、分段线性、三次样条三种插值的方法，改变节点的数目，对三种插值结果进行初步分析。 2、掌握用MATLAB作线性最小二乘的方法。 3、通过实例学习如何用插值方法与拟合方法解决实际问题，注意二者的联系和区别。-1. Grasp by matlab calculating Lagrange, segement linear, 3rd order spline these 3 interpolation method. Analisize the 3 interpolation results by changing the No. of points. 2. Grasp the method of linear minimun 2 product mehtod using matlab. 3. Solve the practical problems though the study of example of how to use interpolation and fitting method. Pay attention to the relation and difference of the 2 methods.

RS纠错编码原理及其实现方法[第三版] 鉴于很多读者来信，特别是初学者对于如何求得RS生成多项式g[x]不是甚理解，特给出计算g[x]的MATLAB程序。(RS error-correcting coding theory and implementation methods [third edition] in view of a lot of letters from readers, especially for beginners on how to get RS to generate polynomial g [x] is not even understanding, give special calculation of g [x] in MATLAB procedures.)
