产生psk调制信号的源程序，并对信号进行成型滤波及上变频(generate PSK modulated signals, and the signals pass the shaping filter and DUC)

说明：  MATLab 信息隐藏实验特别好 MATLab very good information hiding experiment(MATLab very good information hiding experiment MATLab very good information hiding experiment)

matlab 数值分析于应用中的一些很用的 基本代码。(Matlab numerical analysis in the application of some very basic code.)

说明：  优化软件包，MATLAB，应用于YALMIP(Optimization software package, MATLAB, used YALMIP)

说明：  本章的内容更深入MATLAB可视化功能的内核。编写本章的目的有两个：一，使读者更深入地理解高层绘图指令，从而可绘制出更精细更生动更个性的图形；二，使读者能利用低层图形指令和图形对象属性开发专用绘图函数(This chapter more in-depth visualization of the core MATLAB. The purpose of the preparation of this chapter, there are two: First, make readers more in-depth understanding of high-level graphics commands, which can draw out the finer more vivid and personalized graphics 2, so that readers can use low-level graphics commands and graphics object properties developed special drawing functions)

Inverse discrete cosine transform of an image

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )

说明：  基于边缘导向的插值算法 首先估计出低分辨率图像的局部协方差系数，然后基于低分辨率图像的协方差和高分辨率图像的协方差之间的几何二元性，用估计出来的协方差进行插值得到高分辨率图像(Image interpolation based on oriented)
