第4章：聚合函数

说明：  GSL库，以及源程序文件，以及直接安装。不用编译。(The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.)

解决LabVIEW里不能使用数码管字体的方法 用FontCreator软件打开字体，将字体的平台由“Windows Unicode BMP(UCS-2)”改为“Windows Symbol”即可。(Method for solving LabVIEW can not use digital tube font With FontCreator software to open the font, the font platform Unicode BMP Windows (UCS-2) to Symbol Windows can be.)

说明：  TDLAS成像算法，包括福伊特曲线拟合和光谱分析(TDLAS Imaging Algorithms, including Ford Curve Fitting and Spectral Analysis)

网络方面关于ip的得到与获取方面的代码，哈哈哈 -ip on the network and get access to the area code, Ha Ha Ha

仅供学习这个是C语言二级考试中有难度的题(For study only. This is a difficult question in the C Language Level 2 Examination.)

说明：  这个程序能够帮我们从滞回曲线提取骨架曲线，并且可以绘画出来。(This program can help us extract skeleton curve from hysteretic curve and draw it.)

这是一个用于计算蛋白质或短肽二级结构的软件，内附有使用说明！(This is a used to calculate the protein or peptide secondary structure software, included with instructions!)

由ActionList1动态生成树的操作 可方便对权限的管理 可方便对数据字典的管理(Dynamic spanning tree operation by the ActionList1 can facilitate rights management can facilitate the management of the data dictionary)

说明：  研究生C++课上老师讲解的程序，从中能领会到书上学不到的东西（多态与虚函数）(small programs for C++ programming)

检查更改过的文件备份，节省操作时间。 按Ctrl+Alt+F9弹出界面菜单。 显示备份状态和文件大小次数。 当目的地址是网络时，需要帐户和密码。 当正在备份时可以按停止键停止备份。 暂时只有增量备份 备份时间设定，格式可以是 00.00.00 或者 00:00:00。 进程优先算法选中后不影响其他程序工作(默认)。 点击确定保存设定开始计时。 自动启动并计时开始。-inspection changes to the document backup, saving hours of operation. Press Ctrl-Alt-F9 pop-up menu interface. Show backup status and the number of file size. When the destination address of the network, need to account and password. When the backup is at the stop button can stop by the backup. Incremental backup is only temporary backup sets the time, format or can be 00.00.00 00:00:00. Priority algorithm process after the elections does not affect other procedures (default). Click OK to preserve set the timer. Automatically activated and start time.
