通过simulink建模实现不同正弦信号的产生，此模型可作为正弦信号发生器。(Simulink modeling through the implementation of different sinusoidal signal generation, this model could serve as a sinusoidal signal generator.)

matlab一些常用的命令和函数，还包括一些MATLABweb在线平台的资料(matlab some commonly used commands and functions, including some MATLABweb information online platform)

MATLAB 神经网络用于数字识别源程序(MATLAB neural network for digital identification of the source)

说明：  帮助matlab载入.sif文件，从而读取并处理文件内容(Help matlab load. SIF file to read and process file content)

说明：  对于初学者学习matlab很有帮助，尤其在图像处理方面更是很好的啊。(For beginners learn matlab &reg helpful, especially in the image processing is very good.)

低通滤波器，每句程序都有注释，易懂，还有一个实例，便于加深认识(Low-pass filter, each sentence programs have notes, easy to understand, there is an instance, to facilitate a better understanding of)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)

里面汇集了很多经典的pid控制程序，大家可以借鉴哦(Which brings together many of the classic pid control procedures, everyone can learn from Oh)

QR factorization of an m × n matrix A with m ≥ n is a pair of matrices A = QR

说明：  利用粒子群算法优化函数，对Rosenbrock最大值进行优化(Functions using particle swarm optimization, optimization of Rosenbrock maximum)
