MATLAB6.0数学手册 (coefficients Mathematics Handbook coefficients Mathematics Handbook)

该文件中包含HHT（希尔伯特黄变换）的三种MATLAB程序，可以直接使用，非常方便，效果也不错。并附有相关网站。(The file contains the HHT (Hilbert-Huang Transform) of the three MATLAB program that can be used directly, very convenient with good results. Together with related sites.)

matlab 14 -bus data

详细讲述了，matlab与VC++6.0的混合编程(Described in detail, matlab mixed with VC++6.0 programming)

MATLAB语言常用算法程序集:内容超级丰富，且非常全面。(MATLAB language commonly used algorithm for assembly: the super rich and very comprehensive.)

超宽带定位系统，较好的一本书，涉及很多方面的内容(Ultra-wideband positioning system, a good book, involving many aspects)

本程序为Pattern时延差编码水声通信的基本实现程序(Pattern Time Delay Shift Coding)

觉得很好的一个Matlab程序想和大家一起分享，互相学习。(A Matlab program feel good and you want to share, learn from each other.)
