this is k-means clustering algorithm codes in matlab, and it is for beginners

从网上下载的,,用matlab仿真的有源滤波器也就是APF(failed to translate)

说明：  machine vision 工具箱，一直都在用，做机器视觉参考(machine vision toolkit has been used, so machine vision reference)

通信系统链路可靠性和节点可靠性的计算并将两者综合(Communication link reliability and node computing system reliability and a combination of both)

对仿真信号进行快速傅里叶变换，再进行经验模态分解，再对每个分量求FFT(Simulation signal fast Fourier transform, and then empirical mode decomposition, and then seek FFT for each component)

matlab - mapping 4 bit image to 8 bit and 8 bit image to 4 bit

利用谱减法进行语音信号的降噪处理，适用于语音增强领域(Using spectral subtraction to reduce the noise of speech signal, it is suitable for the field of speech enhancement)

说明：  计算电力系统输电网潮流数据的算法 潮流计算(Algorithm for calculating power flow data of power transmission network)

说明：  SGA（Simple Genetic Algorithm）是一种强大的智能多变量优化算法，它模仿种群繁殖规律来进行优化。本SGA可以优化变量，求最小值,最大值（当把函数倒数也就求最小值） 并且支持浮点编码，grey编码，二进制编码；轮赌法选择，锦标赛选择；单点交叉，均布交叉，浮点交叉；单点变异，浮点变异；调用时Genetic（目标函数名） 使用SGA时，首先需要一个目标函数（像AimFunc.m），该函数返回适应度输入变量为待优化变量x输出为一个适应度。然后修改Genetic.m中可以修改的地方(SGA (Simple Genetic Algorithm) is a powerful smart multi-variable optimization algorithm, which mimics the reproduction of law to be optimized. The SGA can be optimized variables, minimum, maximum, (when the function will last for the minimum) and supports the floating-point encoding, grey code, binary code round of betting method selection, tournament selection single-point crossover, uniform crossover , floating-point crossover single point mutation, floating-point mutation called Genetic (objective function name) the use of SGA, first of all need an objective function (like AimFunc.m), the fitness function returns the input variables to be optimized for the output variable x a fitness. Can be modified and then modify the place Genetic.m)

采样QPSK调制误码的仿真程序和星座图的仿真程序(QPSK moduel)
