simulink最小二乘法提前D步预测 （本程序以两步为例）(simulink least squares D steps ahead prediction (an example of this process as two steps))

function for auv id this file is good for estimation

说明：  matlab实验 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？ (matlab experiment with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add random noise in yi (available rand generation (0,1) uniformly distributed random number, or rands generated N (0,1) random numbers), then xi and yi to add a random disturbance polynomial fitting for the three times, compared with the original coefficient . If 2 or 4 times for polynomial fitting, the result?)

递推最小二乘程序，是进行系统辨识很好的程序(Recursive least-squares procedure, is a good program for system identification)

the same with what i have uploaded before.

说明：  序列x（n）的Welch法功率谱估计 用matlab来实现(Sequence x (n) of the Welch method power spectrum estimation using matlab to achieve)
