matlab 例程，粒子群优化算法，很全，希望对大家有所帮助(Matlab routines, particle swarm optimization algorithm, is very wide, and they hope to help everyone)

说明：  用DFT计算连续信号的谱 通过应用 DFT 进一步加深对离散信号 DTFT 和 DFT 的概念及其相互关 系的理解。 =利用 DFT 计算连续周期信号的频谱(DFT calculations using a continuous signal by applying the DFT spectrum of discrete signals to further deepen the concept of DTFT and DFT and their mutual understanding of the relationship. = DFT calculations using a continuous spectrum of periodic signals)

1．编写一个程序，读取一句英语短语，并将其编制成莫尔斯码 莫尔斯码是世界上最著名的编码机制，是1832年由Samuel Morse创立的，用于电报系统使用。莫尔斯码编码规则如下：①字母、数字和一些特殊符号（如圆点、逗号、分号）用一系列指定的点和线表示；②单词之间用三个空格分开，没有点和线；③编码字母之间用一个空格。 (1 write a program to read a word, English phrases, and programmed into the Morse code Morse Ma is the encoding mechanism of the world s most famous, is in 1832 by the Samuel Morse foundation, used for telegraph system. Morse coding rules are as follows: ① letters, numbers and special symbols (such as dot, comma, semicolon) is represented by a series of specified points and lines the words are separated by three spaces, no point and line the code letters with a space. )

GloptiPoly 3: moments, optimization and semidefinite programming. Gloptipoly 3 is intended to solve, or at least approximate, the Generalized Problem of Moments (GPM), an infinite-dimensional optimization problem which can be viewed as an extension of the classical problem of moments [8]. From a theoretical viewpoint, the GPM has developments and impact in various areas of mathematics such as algebra, Fourier analysis, functional analysis, operator theory, probability and statistics, to cite a few. In addition, and despite a rather simple and short formulation, the GPM has a large number of important applications in various fields such as optimization, probability, finance, control, signal processing, chemistry, cristallography, tomography, etc. For an account of various methodologies as well as some of potential applications, the interested reader is referred to [1, 2] and the nice collection of papers [5].(GloptiPoly 3: moments, optimization andsemidefinite programming.Gloptipoly 3 is intended to solve, or at least approximate, the Generalized Problem ofMoments (GPM), an infinite-dimensional optimization problem which can be viewed asan extension of the classical problem of moments [8] .
