说明：  MATLAB产生正弦波源程序txt文件，其中位宽为10，单位长为4096(MATLAB generates a sine wave source txt file, which is 10 bits wide, the unit of length 4096)

三分之一倍频程处理程序,适用于声学及振动信号处理(the third singal )

matlab程序，用于人脸识别的，比较简单的啦，希望对比较没有基础的人有点点用(matlab procedure for face recognition, the relatively simple problem, I hope there is no basis for comparing those who have little use)

matlab中数据分析资料，PPT详细说明相关原理，并有实例代码，包括回归分析等(matlab data analysis data, PPT detail the relevant principles, and examples of code, including regression analysis)

高光谱的MATLAB工具箱，可以参考一下，方便易用(Hyperspectral MATLAB toolbox, you can refer to, easy to use)

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?)

说明：  该程序直接读取excel文件中信号，计算得到信号的自相关函数(The program reads excel files directly in the signal, the calculated autocorrelation function)

在matlab下实现sift描述符，并有测试程序(sift descriptor using matlab，and test procedures are provided)
