粒子群算法（PSO）解决旅行商问题（TSP）的matlab程序。(Particle swarm optimization (PSO) to solve the traveling salesman problem (TSP) in the matlab program.)

包括脚本文件和函数文件形式，含噪脉冲信号进行相关检测,在MATLAB中求图像纹理特征，线性调频脉冲压缩的Matlab程序,isodata 迭代自组织的数据分析，相关分析过程的matlab方法，自己编的5种调制信号，GSM中GMSK调制信号的产生。( Including script files and function files in the form, Noisy pulse correlation detection signal, In the MATLAB image texture feature, LFM pulse compression of the Matlab program, Isodata iterative self-organizing data analysis, Correlation analysis process matlab method, Own five modulation signal, GSM is GMSK modulation signal generation.)

matlab程序，演示了如何画出系统时域和频域的step相应(This demo shows how to plot the time and frequency responses)

alpha稳定分布概率密度函数产生，应用于水声环境中混响噪声信号概率密度的建模，以便于研究水下信号传输(alpha stable distribution probability density function generator, used in underwater acoustic environment reverberation noise signal probability density modeling, in order to study the underwater signal transmission)

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.

说明：  灰度门限化许多情况，图象是由具有不同灰度级的两类区域组成。如文字与纸张、地物与云层（航空照片）。其特点:直方图具有两个峰，分别与两个灰度级范围相对应 。故可选择一个门限，将两个峰分开。(Gray threshold of many cases, the image is gray level of two different regional groupings. If words and paper, surface features and cloud cover (aerial photograph). Its features: histogram has two peak, respectively, with the two gray-scale range corresponding to. So choose a threshold, separating the two peaks.)

关于信息安全的数字水印技术，其的提取与嵌入过程！(On information security digital watermarking technology, the extraction and embedding process!)

说明：  一个长信号进行分析时，可能需要对信号分段，本程序提供一种分段方法(When a long signal is analyzed, it may be necessary to segment the signal)

使用matlab语言编程解决整数规划问题(Using matlab language programming to solve the integer programming problem )

凹边形判定算法，可用Matlab编程,也可用Mathematica软件编程(Concave gon determination algorithm, Matlab programming available, can also be used Mathematica software programming)
