佛洛伊德方法用二值模型来形成多灰度图像的真实效果，希望分享(Digital halftoning is the process of converting a continuous-tone images into strictly black and white images such that, when viewed by the human visual system, the pattern creates an illusion of being a continuous shade of gray. )

张德丰matlab小波分析源代码，从信号时-频联合分析引入小波变换，将信号的多分辨率分析及Mallat算法作为全书的重点，并在此基础上，进一步阐述了双正交小波多分辨率分析、小波包多分辨率分析、提升小波应用，还讲述了小波分析在奇异性检测、去噪及数据压缩中的应用。(Zhang Defeng Matlab wavelet analysis of the source code from the signal- frequency joint analysis of the introduction of wavelet transform, multi-resolution analysis of the signal and Mallat algorithm as the focus of the book, and on this basis, further elaborated biorthogonal wavelet multi-resolution analysis wavelet packet multi-resolution analysis, the lifting wavelet applications, but also about the application of wavelet analysis in the singularity detection, de-noising and data compression.)

能利用发射端的多个天线各自独立發送信号，同时在接收端用多个天线接收並恢复原信息。(Can take advantage of multiple antenna transmitter sends separate signals, while the receiver with multiple antennas to receive and recover the original information.)

这个pdf文件是关于压缩感知的最基础的入门代码，里面有详细的试用说明方法还有讲解(this pdf document presents some basic codes about compressed sensing,including the userguide and explannation)

内点法对非凸非线性规划的解法，求得最优化的解。(Interior point method for solution of non-convex nonlinear programming, to achieve optimum solution.)

这个演示代码解决双目标函数优化问题，用蝙蝠算法和加权求和法。该程序可以扩展到解决多目标。(This demo code solves bi-objective function optimization problems using the Bat Algorithm and the weighted sum method. The program can be extended to solve any multiple objectives.)

matlab code for cohernt communication systems in analog communications.

说明：  little matlab script but still no error

这个程序实现与Matlab的优化工具箱下，用于给图进行边着色。包含了很多图论的程序，如计算最大割集、连通度、最小覆盖边数等等…… (This program is implemented with Matlab Optimization Toolbox for graph edge coloring. Contains a lot of graph theory program, such as the calculation of the maximum cut sets, connectivity, minimal covering the number of edges, etc. ...)
