说明：  最近在研究数字喷泉码，这是对LT码的仿真，系统XP，语言C++(Recent study of digital fountain codes, LT codes which is the simulation, the system XP, language C++)

使用Crank-Nicolson隐式差分格式求解传热方程；第一类边界条件；初始条件已知。(Using the Crank-Nicolson implicit difference scheme for solving heat transfer equation the first boundary condition initial conditions are known.)

1、基本要求： (1)频率测量 测量范围：1HZ~1MHZ，信号为方波、正弦波；幅度为0.1V~5V； 测量误差： 0.1 （以NFC—10A为准）。 (2)周期测量 测量范围：1HZ~1MHZ，信号为方波、正弦波；幅度为0.1V~5V； 测量误差：， 0.1 （以NFC—10A为准）。 (3)脉冲宽度测量： 测量范围：脉冲宽度不超过100μS，信号为脉冲波，幅度为0.1V~5V； 测量误差： 0.1 。 (failed to translate)

用基本粒子群算法来解决优化问题，本程序给出的是测试函数，根据需要可以自行更改适应度函数。(Using particle swarm optimization algorithm to solve the problem, this program is given a test function, you can change the fitness function according to their needs.)

MATLAB图像基本操作命令：imread, imwrite, imshow,figure(MATLAB Image basic operations command：imread, imwrite, imshow,figure)

让ARToolKit支持MQO模型所需的所有函数实现代码，均在对应的GLMetaseq.c中。(Let ARToolKit supports all the functions needed to MQO model codes, both in the corresponding GLMetaseq.c.)

利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以 形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)

PCA程序，用于信号的主分量分析，用过几次，感觉不错(PCA program, the main component for signal analysis, used a few times, I feel good)

自己写的混合遗传算法模板匹配程序，实现功能良好(temple match)

对经典协议LEACH的改进版本，可以出图3个，对初学很有帮助，大家有兴趣的可以看看。(LEACH agreement on an improved version of the classic, you can plot three, very helpful for beginners, we are interested can look at.)
