COMP_EIG

常见的matlab程序。 可以装上图片之后可以直接在matlab上面跑。( it is important and necessary,if necesary,please down it.)

have adapted the PSO to search in binary spaces

最小二乘法椭圆拟合 fit_ellipse( x,y,axis_handle ) x，y为坐标点 适用于一般方程哦。好用(Least squares ellipse fitting fit_ellipse (x, y, axis_handle) x, y for the coordinates of points applicable to the general equation Oh. Use)

power_transient.rar.功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transient.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

说明：  对脑电信号进行5层小波包分解，提取相应的节律波(The EEG signal was decomposed by 5-layer wavelet packet to extract the corresponding rhythmic wave)

模拟一群鸟捕食的情景，从而达到优化目标函数的目的，这就是粒子群算法！起初在可行的空间中随机的产生一群粒子，然后让每个粒子开始在虚拟的空间中向四面八方飞翔，并且每个粒子都记下他们飞过的适应值（也就是目标优化函数）最高的点，而且整个粒子群有一个最高适应值个体，这样，粒子在飞翔的时候尽量朝向自己曾飞过的最好的点和集体的最好的点。最后达到收敛到近似最优点的目的。 (Simulation of a group of birds preying on the scene, so as to achieve the purpose of optimizing the objective function, that is, PSO! At first, where feasible, have a space in a group of random particles, and then let the beginning of each particle in a virtual space to fly in all directions, and each particle they have in mind over the fitness value (that is objective optimization function) the highest point , and the whole particle swarm adaptation has a maximum value of the individual, so that particles in the fly when he had flown as far as possible towards the best point and collective best point. Finally reaching the merits of convergence to approximate most purposes.)
