CMAcode

it is a very essential matlab code.

说明：  用粒子群算法解决背包问题，能得到比较有效的结果(Particle swarm algorithm to solve knapsack problem, the results can be more effective)

matlab从入门到精通，很经典很好的教材(matlab entry to the master, it is a classic good teaching)

pulse with modulation for sinusidal wave making

为带通滤波器，需设置半阶数、高低截止频率和采样频率。保存为function函数的m文件。rar中为一肌电信号。(For band-pass filter, to be set up semi-order, high and low cutoff frequency and sampling frequency. Save it as a function of m file function. rar for a EMG.)

振动和波，MIT 物理III 教材，非常经典。(Vibration and wave, MIT Physics III materials, very classic.)

说明：  用pso对bp神经网络进行优化，对pid控制器进行优化设计(Using PSO to optimize BP neural network and PID controller)

this is function used for local histo gram equalization. you have to pass the window size

电力系统潮流分析matlab 多个ieee测试(electric system power flow)

MVAcltbern illustrates the (univariate) Central Limit Theorem (CLT). n*1000 sets of n-dimensional Bernoulli samples are generated and used to approximate the distribution of t = sqrt(n)*(mean(x)-mu)/sigma -> N(0,1). The estimated density (blue) of t is shown together with the standard normal (red).
