用matlab软件仿真了从卷积码编码，QPSK调制，AWGN信道，QPSK解调，以及Viterbi译码。(Using Matlab Simulate from the coding of convolutional code，Qpsk modulation ，AWGN channel ，Qpsk demodulation and Viterbi decoding。)

对倒立摆系统采用非线性控制方法进行研究的仿真实验结果，取得了预期的效果，程序运行正确。(right inverted pendulum system uses nonlinear control methods to conduct studies on the experimental results, and achieved the desired results, procedures correctly.)

一次可靠度的HLRF算法。随机向量的概率模型采用Nataf分布，考虑变量相关性。验算点搜寻采用U空间的梯度迭代算法。(This is a first-order reliability method based on HLRF algorithm. A multivariate distribution model,Nataf model,is used to generate the random variables. To search the design point in indenpent standard Gauss space, a kind of gradient iterative algorithm is adopted.)

OFDM信道估计，该文件夹包括19个M文件，包括误码率检测，插值计算，瑞利信道等(OFDM channel estimation, the folder includes 19 M files, including bit error rate detection, interpolation, Rayleigh channel, etc.)

《MATLAB应用图像处理》主编徐飞、施晓红，西安电子科技大学出版。用MATLAB来处理数字图像。(" MATLAB application of image processing," editor in chief Xu Fei, SHI Xiao-hong, Xi' an Electronic Science and Technology University Press. To use MATLAB to deal with digital images.)

本程序是针对左端铰支，右端固支的连续梁，并且其中的集中荷载是按作用点在单元中点计算。对于初学者可以做为参考。(This program is for the left end of the hinge support right end clamped continuous beam, and the concentrated load action point unit midpoint. Can be used as a reference for beginners.)

各种chaos相图和相关时序图，比如logistic等(Various chaos phase diagram and related timing diagram，Such as logistic , etc.)
