The time is calculated and converted to 64-bit in the first and second lines and then converted to local time zone before being converted to a SYSTEMTIME structure. Last of all the system time is set.

利用matlab计算主成成分分析法，在word文档里面详细给出了原代码(Matlab calculated using Principal Component Analysis, in the word document which gives details of the original code)

说明：  matlab实验中，用来确认嵌入信息位置的程序，包含了randinterval.m。(matlab experiment, the information used to identify the location of embedded programs, including the randinterval.m.)

说明：  中文版的matlab文档，适合那些和我一样英语不好的同学(Chinese version of matlab files, suitable for those who, like me, English not good students)

Allan Variance Calculation

matlab 的安装实现，帮助大家成功的实现matlab的安装。(Hadoop installation implementation, to help you successfully hadoop installation. )

用Matlab从Excel中导入数据，含虚拟数据和各种导入格式(Import data from Excel into Matlab)

本程序利用Matlab软件仿真了QPSK+瑞利信道及高斯信道，对比分析结果。(This procedure used Matlab software simulation QPSK+ the Rayleigh channel and the Gauss channel, the contrastive analysis result.)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

matlab下实现对有颗粒重叠的情况的计数，读图片-二值化-腐蚀计数-重叠部分hough检测。经过试验，效果不错！(matlab to achieve a particle overlap of the count, read picture- binary- corrosion count- hough overlap detection. After testing, the result is not Wrong!)
