说明：  数学建模里往年试题长江水质运算的求解过程，MATLAB求解1(Mathematical modeling of water quality in the Yangtze River in previous years, questions the process of solving computing, MATLAB Solving 1)

说明：  本程序自己谢的卷积盲分离的程序，调用了几个函数！(This procedure Xie own Convolution Blind Separation of procedures, a few function calls!)

基于马尔科夫随机场的过绿色模拟退火的分割方法程序，包含如何建立马尔科夫随机场。(Markov random field segmentation method for green program based on simulated annealing, including how to build the Markov random field.)

链码，最小包围核的matlab程序，数字图像处理(Chain code, minimum surrounded by nuclear matlab program, digital image processing)

用于数据挖掘，在支持向量机中有重要的应用，主要用于做数据分类。(For data mining, have important applications in support vector machine, is mainly used for data classification.)

Eigenface core matlab code

一个GPS课程的全部代码，含有数据！很实用(MATLAB GPS SCRIPTS-- Charles Meertens and Doug Miller, U. Utah 3Jan95 These scripts were developed for/during a class in GPS and Active Tectonics Department of Geology and Geophysics, U. Utah, Spring, 1994 EXAMPLE RINEX Files (the only ones guaranteed to work this release) CUR10911.94N CUR10911.94O PAR10910.94N PAR10910.94O Main Program scripts: gpshora.m -- function to calculate Modified Julian Day, Homework#1 HW2.m -- Homework#2 read RINEX observation file and plot C/A code vrs. time HW3_plt.m-- Homework#3 read RINEX navigation file, plot satellite positions HW3_3dplt.m-- Same as HW3_plt.m, but 3d position plots HW4.m-- Homework#4 calculate and plot station position as function of time Functions called: calc_nav.m-- calculate satellite position calc_pos1.m-- calculate station position constants.m-- GPS constants coords.m-- convert x,y,z coordinates to lat, long, height date2j.m-- calculate MDJ eccenr.m-- calculate "E" anomally read_nav.m-- Read RINEX Nav file r)

改进的虚拟激励法，用于大型结构的随机频域计算，在建筑、航天、机械领域已得到广泛的应用。(Improved pseudo-excitation method for the large-scale structure of random frequency-domain calculation, in the construction, aerospace, mechanical field has been widely used.)

这是关于数字水印的攻击例程！经过调试，可以放心使用！(This is on digital watermarking attacks routines! After debugging, can be assured use!)

说明：  基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置。(Based on RSSI positioning, the transmitting signal strength of the transmitting node is known, and the receiving node calculates the propagation loss according to the received signal strength. The propagation loss is converted into distance by using the theoretical or empirical signal propagation model, and then the position of the node is calculated.)
