说明：  本程序 包含两个函数 实现了 快速的沃尔什变换(This program contains two functions to achieve fast Walsh transform)

这个小程序可以简单的选取回归分析中box-cox变换的lambda值，通过matlab强大的矩阵运算功能可以通过简单比较RSS值的方式来得到lambda，使用时只需要输入实验值矩阵X和Y即可，然后输入minRSS（X，Y）就能简单明了的看到最优变换参数 （这个程序虽然小但是学习回归分析的初学者学习时都会经过这个算法，上载时因为不到1KB所以我又放了个文本格式的）(This little program can select a simple regression analysis of box-cox transformation of lambda values, through the powerful matlab function matrix calculation can be relatively simple way of RSS to get the value of lambda, the use of only need to enter the experimental data matrix X and Y can be , and then enter the minRSS (X, Y) will be able to see the simple optimal transformation parameters)

说明：   实 现 Cholesky(Cholesky)

chinapub的高清电子书，关于matlab的教程，看着很舒服，不想买纸质教材的同学的首选。反正我是看着很有感觉，推荐一下。(HD eBook chinapub, matlab tutorial, looked very comfortable and do not want to buy the the paper textbooks of students preferred. Anyway, I was watching the great feeling you recommend.)

Long period Fiber Bragg grating simulation.

自学Matlab必备的个小程序代码，里面有十个，需要的下载(Small program code, which must self-Matlab ten, you need to download)

使用差分法解一类Bessel方程在不同边界条件下的离散解(the use of differential method for a type Bessel equation in different boundary conditions of the Discrete Solutions)

this is code for making the excel table in matlab for procesing your data.

程序为常规AM，DSB，SSB调幅信号的调制与解调的MATLAB程序，其中单边带调制用两种方法进行调制：一种为频谱直接变换，另一种为希尔伯特变换实现(MATLAB for norm AM,DSB and SSB modulation and demodulation,besides,modulation for SSB,has tow ways:frequency spectrum transform and hilbert transform)

用于进行聚类分析的matlab工具箱，包括K-means、模糊聚类等。(Used for cluster analysis of the matlab toolbox.)
