对于常微分方程组，很难求得解析解，因此工程上常用数值解法，常微分方程组的R-K解法(For ordinary differential equations, analytical solution is difficult to obtain, so the numerical method used on the project, RK solution of ordinary differential equations )

根据Barabasi等人提出的无标度模型复杂网络生成的preferential attachment原理，生成指定规模的无标度网络的邻接矩阵。(Based on the preferential attachment mechanism proposed by Barabasi et al, the code functions to generate the adjacency matrix for a scale-free network with given size.)

A new carrier synchronizationalgorithm that is carrier recovery strategy is proposed for all digital receivers that is all digital ( A new carrier synchronization algorithmthat is carrier recovery )

生成无标度网络,是研究复杂网络的一个重要基础.(Generate scale-free network is to study the complex network is an important foundation.)

用matlab编写的HDB3码 对于初学信息论编码的同学很有益处(HDB3 code matlab prepared students for the the beginner information theory coding helpful)

msk与gmsk调制解调的仿真程序，仿真结束后将结构写入文件。(structure simulation of msk and gmsk modem program, the end of the simulation will write to the file.)

EOF分解，用ncdisp命令可以看到HadISST_sst.nc是1870年1月至最近的全球SST数据，按比例截取北太平洋（20N-80N 130E-90W）1971年1月至1990年12月240个月份的SST数据进行经验正交函数（Empirical Othorgnal Function）分解,简记为EOF分解，得到该区域该时段的海温时空特征。(EOF decomposition, with ncdisp command can see HadISST_sst.nc is January 1870 to the recent global SST data, in proportion to the interception of the North Pacific (20N-80N 130E-90W) 1971 年 1 月 至 1990 年 12 月 240 month SST data, empirical orthogonal function (Empirical Othorgnal Function) decomposition, abbreviated as EOF decomposition to obtain spatial and temporal characteristics of sea surface temperature in the region of the period.)

matlab的m文件，通过读取sd卡的内容显示成动态图像并生成avi视频文件(matlab m files sd card by reading the contents of the display into a dynamic image and generate avi video files)

code for creating a histogram equalization graph in matlab it convert it first to histogram then perform histogram equlization

海面上一轮船沿直线匀速前行，速度为30公里/小时，船上有一雷达可用来测距、测角，船长关心的是周围目标那些是活动的船，那些是不动的岩石，若是活动的船，请按下面假设，分析有关因素，给出船的运动方向和速度。(ships on the sea along a straight uniform before the trip and a speed of 30 km/hour, On board there is a radar can be used to measure the distance and angle measurement, the captain of concern is around the goal of those activities is the boat. those are immobile rocks, if the ship by the following assumptions, analysis of the relevant factors, the boat is the direction and speed of movement.)
