all modulation of Communication for MatLab

说明：  计算循环卷积，DFT，IDFT,FFT... .. (Computing cyclic convolution, DFT, IDFT, FFT ... ..)

模式识别中的K均值算法，对数据进行归类。程序中，使用了二维数据进行分类。通过修改参数，也可以支持三维或是更高维数的分类。(the K-means algorithm for Pattern Recognition )

说明：  一个线性规划的例子，里边有源数据在里边，比较基础的(A linear programming example, inside the active data in the inside basis of comparison of)

说明：  滤波器设计的目的是对信号进行数据序列的频率变换，去掉其中我们不需要的频率成分，用数字滤波器课实现语音信号去噪(Filter is designed to sequence the signal frequency of the data transformation, which we do not need to remove frequency components, with digital filter class voice signal denoising)

说明：  该源代码是图片切割的详细源代码，是2006年实现的(The source code is a detailed picture cutting the source code, implemented in 2006)

采用专家PID控制器解决三阶传递函数的阶跃响应(PID controller using expert to solve the third-order transfer function of the step response)
