说明：  主动频率偏移法，是用来检测孤岛效应的。采用S函数描述(Active frequency shift method is used to detect island effect. Function described by S)

通过fir1设计FIR滤波器，fir2设计任意频率响应的滤波器，采用卷积计算信号通过系统后响应（还原），采用fftfilt计算信号通过系统后响应，一个长序列和一个短序列的卷积。(Fir1 through FIR filter design, fir2 design the frequency response of any filter, the use of convolution calculation of the signal through the system to respond to (restore), calculated using fftfilt signal through the system to respond to, a long sequence and a short sequence of convolution.)

说明：  编写一个程序，对输入的图像进行哈夫曼编码，显示原图像的熵、编码后的平均码字长度、并能够根据编码重建出图像。 Sobel算子和拉普拉斯算子进行锐化，并比较结果。(Write a program to image the input Huffman coding, the entropy of the original image displayed, encoded, the average code length, and be able to reconstruct the image according to encoding. Sobel operator and Laplacian sharpening, and compare the results.)

说明：  电力系统分析软件最新版本psat2.1.6，可以进行各种计算仿真(power flow analysis psat2.1.6)

Extended Isogeometric code for analysis of plates with two edge cracks.

从倒立摆的数学模型入手，对比了lqr控制器和pid控制器的设计和仿真(From the mathematical model of the inverted pendulum to start, compared to the design and simulation controllers and pid controller lqr)

Design of beamforming antenna

MATLAB，用的是背景差分和实时背景更新(MATLAB, using background subtraction and real-time background update)

很好的CRF的源码，分类方面使用性很强的(it is a good source code code for Condition random flied.It is very strong for classification on images.)
