说明：  根据粒径尺寸和数量生成随机骨料，添加钢纤维及聚丙烯纤维(Generate random aggregate)

用于通信方向中的信道估计，使用的语言是matlab(Used for channel estimation in the communication direction, the language used is matlab)

Softmax用于多分类问题，本例是将MNIST手写数字数据库中的数据0-9十个数字进行分类，其中训练样本有6万个，测试样本有1万个数字是0~9(Softmax for multi classification problems, the present case is the handwritten data MNIST digital 0-9, classification, training samples which have 60,000, there are 10,000 test samples digit 0 to 9)

说明：  利用Matlab进行的一次BCH编码、译码仿真的说明以及程序。(Description and program of a BCH coding and decoding simulation using Matlab.)

经典的MIMO—OFDM外文书籍，是本人迄今为止见过写的最好的。内含matlab代码。(classic MIMO-OFDM book，the best book which i have met。include matlab codes)

常见的地图GIS二次开发有ARCGIS、MO、AO、MAPX、MapXtreme、ASPMAP，但是对于我们初接GPS/GIS项目的人来说，最头痛的问题是无法解决地图，调用GOOGLE的SDK就可以免费使用GOOGLE的免费地图资源，快速构建自己的GIS系统。这项技术可以应用于交通、运输、物流、安防、城市规划、城市管理、林业、农业、工业、灾难指挥、地震灾难等许多行业。采用这种方法应付毕业论文时最省事了，连数字化地图的步骤都省了，别人开发GIS系统要几个月，用GOOLE二次开发，只要短短的几天。我有一个学生，程序明明用GOOGLE的二次开发，但是在论文里大谈自己是用ARCGIS开发的，几个答辩老师愣是没瞧出来，这位学生，轻轻松松获得答辩高分。 本程序可以工作于vs.net各种版本，我编译时采用vs2008，asp.net采用3.5的支持库。(Common secondary development of GIS maps has ARCGIS, MO, AO, MAPX, MapXtreme, ASPMAP, but for us to pick beginning of GPS/GIS project for people who can not be solved the most headache problem is that maps, call the SDK can be free of charge GOOGLE GOOGLE maps using free resources to quickly build their own GIS system. This technology can be applied to traffic, transportation, logistics, security, urban planning, urban management, forestry, agriculture, industry, disaster command and earthquake disaster, and many other industries. When using this method to cope with dissertation The easy, and even the digital map of the steps are saved, others take a few months development of GIS systems, with GOOLE secondary development, as long as only a few days. I have a student, the program is clearly using GOOGLE secondary development, but the paper was much talk that he is using ARCGIS developed several defense teacher Leng Shimo Look out, the students, easy access to defense scores. This proc)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

瑞利衰落信道建模 误码率、传输速率 多径传输(Rayleigh fading channel modeling Bit error rate and transmission rate Multipath transmission)

说明：  该程序能解决均匀面阵的二维DOA估计问题(The code can solve the problem of 2-D DOA estimation for uniform array.)

mapinfo图斑操作使用教程，非常实用，值得参考学习。(the mapinfo polygons operations using the tutorial, very practical, it is also useful to learning.)
