Low density parity check matrix(Description A program written for generating LDPC matrix in the as pattern as discussed in the research paper , " Time varying periodic convolutional codes with low density parity check matrix" by Alberto jiménez Felströ m and Kamil Sh. zigangirov IEEE Transaction on information theory vol 45 no 6 sept 1999. pages 2181-2191)

说明：  该文件包含用MATLAB实现的OFDM 的源程序(Channel estimation for a MIMO-OFDM system)

立体图像质量评价，文章以cyclopean image为核心构建算法。(Full-reference quality assessment of stereopairs accounting for rivalry)

PID用于机器人路径控制的MATLAB程序,路径选择是一个简简单的正弦函数.控制参数是速度和角速度.，已通过测试。 (The MATLAB program PID control for robot path, the path selection is a sine function simply control parameters and angular velocities. Has been tested.)

说明：  三相三线制并联型有源电力滤波器的设计与研究,一篇3万字左右的论文，还是不错的(Three-phase three-wire shunt active power filter design and research about a 30,000-word thesis, or good)

极化SAR分类方向的很好的入门PPT资料，对各种相干、非相干分解方法以及监督、非监督分类方法做了简单的阐述(polarimetric SAR decomposition and image classification )

图象处理的功能和应用 很实惠的很好的,请提宝贵意见(Image processing functions and applications are of very good benefits, please mention the valuable advice)

张量的模式展开是一个基本的技术，已有各种代码展开结果不尽相同，本代码是根据张量研究领域权威文献“Tensor Deco们positions and Applications”中的公式编写，并经过多次实例验证，与理论描述相符。文件包括两个m文件，一个是按模n展开，而另一个是逆变换，即按模n叠合。(unfolding of the tensor mode is a basic technology, there are a variety of code to make different result. However this code is written by referring to the authority of the tensor field of research literature Tensor Deco their positions and Applications and after several instances verification, is consistent with the theoretical description. The documents include two m-files, one is unfold.m, and the other is the inverse transformation, that is refold.m.)

说明：  2019年第16届华为杯数学建模F题第一问的代码(Code of the first question of mathematical modeling F of the 16th Huawei cup in 2019)

对图像进行对比增强。没有用matlab命令 而是内核 想研究的同志可以(right image contrast enhancement. Not using Matlab order to study the kernel but the comrades can s)
