说明：  两份Matlab的资料，一个是关于如何与VC接口调用Matlab的程序；一个是介绍matlab如何使用(Matlab two information, one is on how to call Matlab and VC interface procedures one is to introduce how to use matlab)

一种基于AT89S52单片机的光电开关转速测量系统的设计。系统采用反射式光电开关产生与齿轮相对应的脉冲信号，使用AT89S52单片机采样脉冲信号并计算每分钟内脉冲信号的数目，即电机对应的转速值，最终系统通过数码管实时显示电机的转速值(A photoelectric switch based on AT89S52 Microcontroller speed measurement system design. The system uses a reflective photoelectric switch with the gear corresponding to the pulse signal, the microcontroller AT89S52 sampling pulse signal and calculate the number of pulse signals per minute, the motor speed value corresponding to the final system in real time by digital tube display the value of the motor speed)

说明：  Quick Sort an implementation in c++language. may it help others in their projects

资源描述本源码是headfirst c#书中的赛狗游戏源码，已经亲身跑过这个源码，没有问题。该例子对于对象继承的学习很适合。另外这本书的例子都很好玩，我会继续上传其他例子的。

Modbus 协议是应用于电子控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通信。它已经成为一通用工业标准。 本程序使得Modbus 协议的开发变得简单，提高学习和研究的效率。

The first thing we do there is to verify if a device context has been supplied. If that s not the case, we can t create a font so we throw an exception. We then ask OpenGL to generate a continuous set of 255 diplay lists that will be used for 255 characters. (The first thing we do there is to verify if a device context has been supplied.

对GIS的开发进行一小部分的分享，今后还开发更多。(A small part of the development of GIS is shared, and more will be developed in the future.)
