从变量可见性角度分析，Matlab程序运行过程中（以下不特别说明都是指在Matlab程序中），不同形式的变量可见范围源于于面向对象编程的概念.(variables can be seen from the point of view of analysis, Matlab procedures in the process (not refer specifically explain procedures in Matlab), different forms of variable can be seen in the area stems from the object-oriented programming concepts.)

说明：  This code is related to the course Digital Communications. It makes a simple communication system which uses AWGN and QPSK

matlab code for implementation of y bus

这个程序是希尔伯特黄变换的希尔伯特变换部分的MATLAB仿真程序。(This program is Hilbert Huang Transform Hilbert transform part of the MATLAB simulation program。)

matlab 绘制偏微分方程的函数 对于绘制偏微分方程的函数和边界曲线非常有参考性(matlab draw a function of partial differential equations for the mapping function of partial differential equations and the boundary curve of a very good reference of)

说明：  分别采用感知机算法、最小平方误差算法、线性SVM算法设计分类器，分别画出决策面，并比较性能。(Perceptron algorithm were used, the least square error algorithm, linear SVM classifier algorithm, respectively, making face paint, and compare performance.)

QPSK波形及其经过带宽为4hz的带通滤波器(QPSK waveform and its after 4HZ bandwidth of the bandpass filter)

计算快速ICA（独立分量分析）的方法，结果表明，该方法行之有效 (Calculation of fast ICA (Independent Component Analysis) method, results show that the method worked well)

这是加权网络中节点强度和权重都是幂率分布的模型。(This is a node-weighted network strength and weight distribution are the model of power.)
