介绍了垂直同步的相关知识。 介绍了一种简单的计算帧速（FPS）的方法。 最后，我们列出了一份完整的天体动画程序清单。 (Introduce a vertical synchronization knowledge. Introduce a simple calculation帧速(FPS) method. Finally, we have listed a complete list of animation objects.)

我上机实验时在matlab环境上编写的一个关于滤波器的程序文件。(This is a file about filter builded in matlab.)

说明：  从方程组中消去一些未知函数及其各阶导数，得到只含有一个未知函数的高阶常系数线性微分方程(Eliminated from the equations of some unknown function and its first derivative, the only unknown function contains a higher-order linear differential equations with constant coefficients)

潮流计算的好程序，c++，潮流计算的好程序，c++(Good program flow calculation, c++)

kaiser窗函数的用法，这是一个资料上的，经过验证了，希望帮得到你。(usage of the kaiser window function, which is an information, after the verification, and hope to help get you.)

BCH码的原理及BCH (15, 5)码MATLAB编译码仿真过程(BCH code of principles and BCH (15, 5) code decoding simulation MATLAB)

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

进程操作的类,可以从进程名枚举进程PID,也可以从窗口标题查找,打开进程,读取长整型,写入长整型,读取字节数组,写入字节数组.压缩包内包含有一个破解示例,破解掉一个判断密码是否正确的程序(仅在内存中进行,不破坏原文件)(Process operations class, you can enumerate the process name from the process PID, you can search for the title from the window, open the process, read a long integer, write long integer, byte array to read, write byte array. Tarball sample contains a crack, break out a password to determine whether the correct procedure (only in memory, not a destruction of the original document))

要在VC中成功编译Matlab引擎程序，必须包含引擎头文件engine.h并引入Matlab对应的库文件libmx.lib、libmat.lib、libeng.lib(VC to successfully compile Matlab engine procedures, must include the engine header files engine.h and the introduction of the corresponding Matlab library files libmx.lib, libmat.lib, libeng.lib)

关于matlab主元分析的一个简单单易懂的实例，可供初学入门者参考学习。 (On the matlab principal component analysis is a simple single-understand examples, for novice beginners for reference.)
