In computer science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. PSO optimizes a problem by having a population of candidate solutions, here dubbed particles, and moving these particles around in the search-space according to simple mathematical formulae over the particle s position and velocity. Each particle s movement is influenced by its local best known position and is also guided toward the best known positions in the search-space, which are updated as better positions are found by other particles. This is expected to move the swarm toward the best solutions.

说明：  使用时打开此例题目录下pic中的图片，然后依次单击按钮“转”、“1”、“2”、“3”、“4”和“5”，就可以实现精确的车牌定位。(use this example to open directory pic of pictures, then click the button "turn", "1", "2", "3" and "4" and "5", can achieve precise positioning of the plates.)

这是我意外发现的一个非常好的学习资料，希望对新手学习matlab有帮助(This is what I accidentally found a very good learning materials, hope to help novice to learn matlab)

analog modulation and coding technique

用矩量法计算细线天线的散射场，使用了脉冲基函数．(Using moment method calculation of the scattering field of thin wire antennas, use the pulse basis function.)

本程序是在不同小波包基的情况鲁昂下研究峰均功率的程序(This procedure is different from the case of wavelet packet basis of Rouen peak to average power under the procedures)

AM Modulation (informatif signal, redressement, filter, demodulation, filter, amplification)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.

用matlab编写的一个地球图片程序，很有意思。(Using matlab to prepare a global picture of the process, a very interesting question.)
