matlab codes for ant colony optimization

在MATLAB上运行，程序主要功能为改变输入图像的灰度和提取。(In MATLAB run, the program main function is to change the input image intensity and extraction.)

该文件为libsvm核心数据集文件，用于测试libsvm安装和学习开发。(This file is libsvm core data set files for testing libsvm install and learn to develop.)

ISAR目标仿真回波在加入不同噪声下利用不同时频分析工具进行分析的MATLAB例子(MATLAB examples of ISAR target echo signals simulation and the time-frequency analysis with different time-frequency tools when adding different noise to the echos)

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一入门与提高(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first entry and improve)

In this project, the standard particles swarm optimization - named here (MyPSO) is simulated and tested by five well-known benchmark functions (Sphere, Ackley, Rastrigin, Rosenbrock and Schwefel p2.26). Then, a new mechanism- named here (Improved MyPSO) is introduced to improve the performance of the standard particles swarm optimization to achieve better results and avoid stagnation at bad results. This new mechanism is also tested by the same benchmark functions. The results of improved PSO are then compared with those of standard PSO and different published improved PSO (SPSO, PSO-XD, CPSO-S and PSO-P5).

The following Matlab project contains the source code and Matlab examples used for 1d blaise filter for quick smoothing without curve fitting toolbox. This is an old filter I used before enjoying more sophisticated options Matlab now offers. Easy to modify, change weights and window size according to the type of noise present.

几种常用分布（如泊松分布、正态分布、指数分布、均匀分布）随机变量的matlab实现方法。(Surement distribution (eg Poisson distribution, normal distribution, exponential distribution, uniform distribution) random variable matlab implementation methods.)

FIR数字滤波器设计，分别让满足所设计的滤波器的通带、过渡带、阻带频率特性的正弦波通过滤波器，验证滤波器性能；(FIR digital filter design, respectively, so that the design meets the filter passband, transition zone, stop-band frequency sine wave pass filter characteristic, verify filter performance )

通过对各种窗函数的matlab仿真，比较各种窗函数的频谱特性，并且将不同的窗函数加权到脉压信号上，观察特性的优劣(Based on all kinds of window function of matlab simulation, compare all kinds of window function, the characteristic of the frequency spectrum of and different window function weighting to the pulse pressure signal, the merits of the observed features)
