小波分析，可直接使用。可用于气象数据，入门者方便使用(Wavelet analysis, can use directly. Can be used for meteorological data, even beginner ease of use)

说明：  （回归分析） 考察温度x对产量y的影响，测得下列10组数据： 求y关于x的线性回归方程，检验回归效果是否显著，并预测x=42℃时产量的估值及预测区间（置信度95 ） ((Regression analysis) x on the output of the temperature study of the impact of y, measured the following 10 sets of data: for y on x of the linear regression equation to test whether the effect of a significant regression and prediction when x = 42 ℃, and the valuation of yield prediction interval (95 percent confidence level))

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

这里有拟合还有误差分析的基本所有函数，是经济学学习过程中的(There is also the error of fitting all the basic functions of the learning process in economics)

关于自适应很好的例子 可以参考参考自适应滤波matlab源程序(Adaptive good example can refer to reference)
