很好的matlab教程，非常不错。新手到 高手的必读教程。望大家多(good Matlab Directory, very good. Newcomers to the master of study guide. Everyone was looking after another!)

Program of Particle Swarm Optimization

用matlab实现1000组复数数据的拟合，并计算拟合函数的归一化均方误差（NMSE）.(1000 groups using matlab fitting complex data, and calculate the fit function normalized mean square error (NMSE).)

In this paper, we consider the use of Modulation Spectra for voice pathology detection and classification. To reduce the high-dimensionality space generated by Modulation spectra

柯尔莫哥洛夫熵（Kolmogorov熵，以下简称K熵）是刻划混沌系统的一个重要的量。在不同类型的动力学系统中，K熵的数值是不同的。本程序可以计算kolmogorov熵(Kolmogorov entropy (hereinafter referred to as K entropy) is an important quantity for describing chaotic systems. In different types of dynamical systems, the K entropy is different. This procedure can calculate Kolmogorov entropy.)

主要讲解了matlab在数学建模中的基础运用,对初学者较有意义。(the use of matlab in the CMCM.)

说明：  随着信息容量的增加和频率资源的稀缺，为提高单位频带利用率，在微波通信系统中越来越多地采用多电平多相位的复杂信号调制方式，尤其是正交幅度调制(QAM)得到了大量的应用，从早期的4QAM到今天的16QAM。高阶QAM调制大容量数字微波通信系统为了保证服务质量，降低误码率，(long with the increase of information capacity and frequency resource scarcity, for improving the utilization ratio, unit of microwave communication bandwidth used more and more in the system of multilevel much phase modulation method complex signal amplitude modulation )

matlab版的Piii频率分析绘图计算程序源代码(The frequency of Piii matlab version of the drawing program source code)

a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery data and two bit Authentication data of the image block into the least significant bits (LSB) of its corresponding mapping block.The integrity of a test block is decided by comparing 2×2 non overlapping block of the test block with its corresponding mapping block. Experimental results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well as in tamper recovery of the image.
