说明：  CDMA系统中的功率控制，仿真实现了CDMA系统的多种情况下的功率控制(CDMA power control system, simulation of the CDMA system to achieve a variety of power control in case of)

简单演示了VC-Matlab混合编程的一种方法。(Simple demonstration of the VC-Matlab mixed programming methods.)

PID控制直流电机源码（simulink），可以直接运行。(PID control of DC source, can be directly run.)

说明：  求R波及极大值的matlab程序，实验有效。(Find the maximum value of R matlab program affected the experimental effective.)

说明：  编写程序：基类base，有一个私有数据成员n，派生类Derived公有继承基类base，Derived中新增加一个数据成员m(Programming: the base class base, there is a private data member n, the derived class Derived inherits the base class public base, Derived add a new data member m)

理论计算PN结中电荷分布曲线，电场分布曲线以及能带图理论值，并用matlab进行数值求解，分析差异。(The theoretical calculation of the charge distribution curve of the PN junction, the electric field distribution curve and the energy band diagram of the theoretical value, and solved numerically using matlab to analyze the differences.)

基于铌酸锂MZ调制器，通过展开，计算其三阶互调失真以及SFDR等(Based on lithium niobate MZ modulator, by expanding to calculate the third-order intermodulation distortion and SFDR etc.)

本程序为仿真光学CCD进行全息成像的仿真程序，对于理解全息成像有一定帮助(The program for the simulation of holographic optical CCD imaging simulation program, for holographic imaging understand some help)

归一化切割和图像分割算法及其论文,归一化分割不仅度量了不同分组之间总体不相似性，同时度量了分组内的总体相似性(Normalized cuts and image segmentation algorithm and its papers, normalized measure divided not only between the different groups no overall similarity, while the overall measure of similarity within groups)
