8-words-circling-the-car

这是一个希尔伯特变换的程序包，里面共有5个程序，可用于普通的希尔伯特变换(This is a Hilbert transform of the package, a total of five procedures which can be used in ordinary Hilbert Transform)

替代数据生成算法。包括常用的随机相位法(shuffle.m and surrogate.m)，周期随机相位法(cycleshuffle.m)和PPS算法(pps.m and findrho.m).(Surrogate data algorithms, including the usual approaches (shuffle.m and surrogate.m), the cycle shuffle version (cycleshuffle.m) and the PPS algorithm (pps.m and findrho.m). )

Base class for all test runners.

说明：  能够实现电力系统信号得EEMD分解，可用于电力系统低频振荡信号分解(It can realize EEMD decomposition of power system signals and can be used for power system low frequency oscillation signal decomposition)

％ 文件名：randlsbget.m ％ 程序员:余波 ％ 编写时间:2007.6.25 ％ 函数功能: 本函数将完成提取隐秘于上的秘密信息 ％ 输入格式举例:result=( scover.jpg ,56, secret.txt ,2001) ％ 参数说明: ％ output是信息隐藏后的图象 ％ len_total是秘密信息的长度 ％ goalfile是提取出的秘密信息文件 ％ key是随机间隔函数的密钥 ％ result是提取的信息 function result=randlsbget(output,len_total,goalfile,key) ste_cover=imread(output) ste_cover=double(ste_cover) ％ 判断嵌入信息量是否过大 [m,n]=size(ste_cover) frr=fopen(goalfile, a ) ％ p作为信息嵌入位计数器将信息序列写回文本文件 p=1 ％ 调用随机间隔函数选取像素点 [row,col]=randinterval(ste_cover,len_toal,key) for i=:len_toal if bitand(ste_cover(row(i),col(i)),1)==1 fwrite(frr,1, bit1 ) result(p,1) else fwrite(frr,0, bit1 ) result(p,1)=0 end if p==len_total break end p=p+1 end fclose(frr) ()

说明：  用来进行双边带幅度调制DSB_AM的MATLAB源程序。(Demonstration script for DSB-AM. The message signal is+1 for 0 < t < t0/3,-2 for t0/3 < t < 2t0/3, and zero otherwise.actually means Rx(m-1). )

reflectivity group delay and dispersion of a sampled fiber Bragg grating with periodic phase shifts at each sampling period

图像处理读入图像序列，可以读入20张图像每次，只要你设定参数(Read image processing image sequences, can be read into the 20 images each, as long as you set the parameters)

matlab函数查询手册，很实用的辅助工具(the matlab function query manual, very useful aids)

建立包含直驱型风力发电机、单级式光伏发电系统和储能蓄电池的风能与光伏混合微电网模型。混合微电网在并网运行时，通过储能蓄电池平滑风能和光伏电源的输出功率波动，维持公共连接点电压。(A wind power and photovoltaic hybrid microgrid model including direct drive wind turbine, single-stage photovoltaic power generation system and energy storage battery is established. When the hybrid microgrid is connected to the grid, it can maintain the voltage of the common connection point by fluctuating the output power of the energy storage battery smoothing wind energy and the photovoltaic power.)
