说明: (拟合)
用给定的多项式,y=x3-6x2+5x-3,产生一组数据(xi,yi,i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数),然后用xi和添加了随机干扰的yi作的3次多项式拟合,与原系数比较。
如果作2或4次多项式拟合,结果如何?
((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)

《實戰C++ — 八個別具特色的實作經驗》與目前市面㆖ 眾多C++ 書籍的最大不同,在於
本書既非基礎觀念之教㈻ 書籍,亦非開發工具之使用手冊,而是以「㆒ 章㆒ 專案」的方式,
從實際應用面引領讀者領略C++。
本書是《The Art of C++》的㆗ 文譯本。原作者Herbert Schildt 是㆒ 位㈻ ㈲ 專精、著作等身的
IT 技術作家,其作品普遍獲得良好評價。(err)
