现实先序遍历二叉树！

说明：  龙格-库塔方法的使用，例子 求y’=y-2x/y，y(0)=0。 解：输入X0=0，X1=1，H=0.2，N=6。()

航空影像的空间后方交会程序,用共线方程,已知地面控制点的情况下,解求像点坐标matlab完成矩阵运算，程序简洁实用(Aerial Images of the space resection procedure, with a total line equation, known ground control points of the case, the solution coordinates matlab order to complete the image point matrix operations, the program simple and practical)

说明：  一个多输入多输出小波网络的源程序，用matlab编写，能够实现对时间序列数据的训练预测(A multi-input multi-output wavelet network' s source code, written with matlab, can be achieved on the training time series data forecasting)

最最精简的射频对传例程，对于我们自己设计的硬件性能验证和无线代码的入门，都非常有帮助。(Most streamlined RF to pass routine performance verification and entry for hardware wireless code are very helpful.)

SOCKET界面的编程，TCP程序的实现。(SOCKET interface programming, TCP program implementation.)

live555 rtsp build in vs2008 and vs2015. also make testRTSPClient execute project

说明：  小型的商品管理系统，提供商品和供应商的查询、添加、删除、编辑等功能，以及对商品管理系统业务的权限管理。本系统使用链表结构操作数据，提高了数据处理的效率。设计若干类和文件实现，用链表来存储商品的基本信息以及供应商，系统角色信息等。(The small commodity management system provides the query, addition, deletion, editing and other functions of commodities and suppliers, as well as the right management of the business of the commodity management system. The system uses linked list structure to operate data, which improves the efficiency of data processing. Some classes and files are designed to store the basic information of goods and the information of suppliers and system roles.)

非接触式IC卡开发板源代码，可应用于电子通信领域(Non-contact IC card development board source code)

使用三叉链表实现的哈夫曼树,统计inputfile1.txt中各字符的出现频率，并据此构造Huffman树，编制Huffman 码；根据已经得到的编码，对01形式的编码段进行译码。 具体的要求： 1．将给定字符文件编码，生成编码，输出每个字符出现的次数和编码； 2．将给定编码文件译码，生成字符，输出编码及其对应字符。 (Emergence of the frequency of each character in the trigeminal lists using the Huffman tree, statistics inputfile1.txt, and accordingly the Huffman tree structure, preparation of Huffman code according to the coding has been. 01 to form the code segment for decoding. Specific requirements: 1 coding the given character file, generating the encoding, and outputting the number and encoding of each character 2 will be given the encoding file decoding, generating the character, the output code and its corresponding character.)
