Matlab实现史密斯圆图的绘制程序。 这个Matlab程序，绘制史密斯圆图，同时绘制反射系数。(Matlab Smith chart drawing program. The Matlab program to draw a Smith chart, draw the reflection coefficient.)

个人编写的应用于机械行业的arx开发函数，足够用的(Individual applications written in the mechanical industry ARX development function)

Great Way to start programming !

PSNR for image processing

在simulink中搭建Buck-Boost开环电路，但这种开环电路不好调整输出电压，于是又搭建了一种简单闭环电路(Buck-Boost open-loop circuit is built in simulink, but this open-loop circuit can not adjust the output voltage, so a simple closed-loop circuit is built.)

前向反馈BP神经网络算法matlab源程序，有详细的注释，是学习编写程序的基本例程。(Feedback prior to the BP neural network algorithm matlab source code, there are detailed notes, is to learn the basic programming routines.)

分支定界法求解TSp问题的分析研究以及matlab实现(Branch and bound method to solve the problem described TSp)

对frame1进行一个简化的帧内编码方案: A)将图像分为8x8的块. B)将图像每一块做DCT2变换. C)将DCT系数采用11.ppt page 35的亮度量化表量化. 量化系数 = 取整 (DCT系数./量化表). D) 统计整个图像中非零量化系统的比重, 该比重可反映什么? E) 将量化系数进行 IDCT2, 绘制出重建图像.(a example for matlab to deal with a picture)

DEA数据包络分析，MATLAB实现，两种模型(DEA--Data Envelopment Analysis)

仿MATLAB矩阵C++运算库,包括加、减、乘、除、点加、点减、点乘、点除、赋值、转置、rank、det、eig、svd、pinv、power等的运算。inv运算使用pinv运算。最难实现的是非方阵的除法。(MatLab Matrix simulator)
