PCA-SIFT

正负1隐写matlab实现，虽然简单但很使用(Steganography matlab achieve plus or minus 1)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

matlab/simmulink中Selector模块各个选项的详细示例。只是一个小小的示例，想详细了解Selector的话可以看看，会熟练应用的大神可以无视了。(The matlab/simmulink Selector module options detailed example. Just a small example, would like to learn more about the Selector, then you can take a look at.)

即奇异谱分析，广泛应用于信号识别与预测。(SSA, that singular spectrum analysis, widely used in signal recognition and prediction.)

矩形波导三维仿真程序，输入矩形波导的尺寸，函数可以计算出矩形波导TE波，TM波的的三维矢量图(the simulation program of the rectangular waveguide. input the size of the waveguide, the program can calculate the TE and TM wave of the waveguide and plot the three dimession figure.)

说明：  实现高低频功率自动分配，对于混合储能系统优化利用具有重要的意义。(the simulattion program realize the parallel of the battery and the super-capacitor)
