Differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on.

是空间普中的经典music算法仿真程序，其中包含了4中算法的对比(this is a classical MUSIC algorithm what is about the spatial spectrum estimation)

用newmark-beta法计算单自由度结构输入地震动后的位移时程曲线，该函数可应用于各种周期的结构的反应，不存在中心差分法的问题 (newmark-beta method)

匈牙利算法的MatLab实现，用于求解关于最大连接(MatLab implementation of the Hungarian algorithm for solving the maximum connection on)

说明：  简要介绍了OFDM的发展状况及基本原理, 文章对OFDM 系统调制与解调技术进行了解析，得到了OFDM 符号的一般表达式，给出了OFDM 系统参数设计公式和加窗技术的原理及基于IFFT/FFT 实现的OFDM 系统模型，阐述了运用IDFT 和DFT 实现OFDM 系统的根源所在,重点研究了理想同步情况下,保护时隙(CP)、加循环前缀前后和不同的信道内插方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系统模型的基础上,用MATLAB语言实现了传输系统中的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,研究保护时隙、循环前缀、信道采用LS估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。(Generation of OFDM Communication System)

说明：  这里还有一个matlab和VC混合编程的，希望对学习matlab的人有帮助(Here is a matlab and VC programming mix, and want to help people to learn matlab)

matlab开发的记事本程序，能够实现简单的文本编辑工作(Notepad matlab development process to achieve a simple text editor)

this file is for restructure

说明：  通用NSGA2程序，里面有详细的注释，亲测可用(General NSGA2 program, which has detailed notes, pro test available)
