在振动台试验后由测得的加速度值两次积分求位移(Acceleration of displacement)

实现发动机性能的计算，在matlab环境下简单可靠的运行(this can use at matlab to engine)

说明：  抽象类以及纯虚函数的相关笔记。Figure作为基类，派生出Circle，Square(Abstract classes and pure virtual functions related notes. Figure as a base class, derived Circle, Square)

Adaptive Communication Environment

计算机械振动烈度，由采集的振振动位移数据来求得可直接使用。 (Calculation of the mechanical vibration intensity, obtained by the vibration vibration displacement data collected can be used directly.)

Windows下的ICMP封装(Clcmp class which can echo)

适合卫星通信本科学生借鉴。主要为卫星转发器仿真设计。可以实现上下变频，非线性放大器实现和卫星转发器实现。(Satellite transponder Simulation Design。Achieve Frequency conversion)

Matlab高级讲义-控制系统的数学描述与建模(Matlab senior notes- the mathematical description of the control system and modeling)

说明：  该代码是一个基于MATLAB语言编辑的四面体有限元长应变四面体算法，包含一个例子很实用，性能稳定。感谢大家的分享。(This code is a kind of constrain Tetrahedral fem compution on MATLAB。there are total code and an example in cube。It is very practical and stable。thank you for your exchanging。 )

arduino下的增量编码器库文件，很好用的(Incremental encoder library files under Arduino )
