利用蚁群算法对pid进行参数优化，里面有源代码和一些代码的注释(Using ant colony algorithm to optimize the parameters of pid, there are source code and some code annotations.)

无控件版Delphi图书管理系统源码Access数据库，采用面向对象的程序设计理念编写，程序无使用第三方外部控件，因此在Delphi7环境下可直接编译代码，运行时请注意access的路径，运行界面效果如演示截图所示。 　　本套系统主要用来管理图书资料的，并不包括类似图书馆那样的租借模块，基本是数据库的简单操作，可修改成其它档案资料管理系统。

说明：  [Numerical Methods in Engineering with MATLAB]2005 and midterm exam problems at Ulsan National Institute of Science and Technology

说明：  数字图像处理应用广泛，在工业中也是如此，此程序用于工业领域中的表盘识别(Digital image processing is widely used, so is the industry, this program is used in the field of industrial dial recognition)

说明：  C++编程指南电子版 ，林锐博士的多年C++编程经验总结，其中C++编程中需要注意的问题和编程技巧总结的不错 (C++ programming guidelines electronically, Dr. Lin Rui years of Experience in C++ programming, including C++ programming problems that need attention and good programming skills summary)

模拟电路基本知识讲解，非常适合初学者。强烈推荐(The basic knowledge of analog circuits is very suitable for beginners.)

部分线性代数计算算法，个人精力有限只整理的这么一点。-Linear algebra part of the calculation algorithm, the individual efforts of so limited that only compiled.

说明：  下面是一个结构体声明： struct box { char maker[40] float height float width float length float volume } a. 编写一个函数，按值传递box结构，并显示每个成员的值 b. 编写一个函数，传递box结构的地址，并将volume成员设置为其他三维长度的成绩。 c. 编写一个使用这两个函数的简单程序 (Here is a structure declaration: struct box {char maker [40] float height float width float length float volume } a. Write a function that is passed by value box structure, and shows the value of each member b . to write a function, passing the address box structure and volume settings for the other three members of the length of the results. c. use these functions to write a simple program)
