This program give examples on how to sample from normal distribution

******************iterator模式***********(***************************** iterator pattern)

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

混沌在加密方面的典型应用，不错的报告。。。。(Typical applications of chaos in the encryption, good report..)

基于mantlab编程实现学生成绩管理，包括学生信息的增加、删除、查询等，增强了容错处理，能很好地运行。(Based mantlab programming of student achievement, including student information to add, delete, query, etc., enhances the fault-tolerant and can run well.)

科斯塔斯环的matlab仿真过程，可以直接运行，其模拟了GPS中载波环的运作过程(Costas loop the matlab simulation process can be run directly simulate GPS carrier ring operation)

the threshold is determined and the foreground and background are seperated

线性调频信号实现以及匹配滤波器进行脉冲压缩(linear frequency signal)

Using magic time-step in a one-dimensional FDTD grid, implement total-field/scattered-field wave-source condition
