对阈值隐藏图像的提取。已经经过阈值隐藏算法隐藏的二值图像，通过此算法进行信息提取。(Hidden images on the extraction threshold. Hiding algorithm has been hidden threshold binary image information extracted by this algorithm.)

18 Random Number Generation - a large collection of random number generators.

说明：  设计产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，使用矩形窗设计不同特性的数字滤波器对信号进行滤波处理，分析所设计滤波器(画出了频率特性曲线)，并对信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，同时设计出了一个友好的人机交互界面。(Designed to produce a continuous signal, including low frequency, medium frequency, high frequency components, its sampling, spectral analysis, using rectangular windows of different characteristics of digital filter design the signal filtering, analysis of the designed filter (to draw the frequency characteristic curve), and signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, the mean time, a friendly interactive interface.)

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

该代码利用matlab，根据各类边界条件的设定，实现了FDTD的算法。( This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a three-dimensional Cartesian space lattice comprised of uniform cubic grid cells.)
