机械优化设计主要包括建立优化设计问题的数学模型和选择合适的优化方法及程序两方面的内容.基于二次插值法的基本原理,通过实例,编写MATLAB程序进行求解,计算结果说明了二次插值法是一种求解一元函数极小点问题最优解的可行高效的方法.(Mechanical optimization design includes a mathematical model to optimize the design of the problem and choose the appropriate two aspects of optimization methods and procedures based on the basic principles of quadratic interpolation method, is solved by way of example, the preparation of MATLAB, the results illustrate the quadratic interpolation method is a function of one yuan to solve the problem of the optimal solution of the minimum point efficient way possible.)

对于一维时间序列 ，可通过延迟坐标相空间重构法扩展到高维空间，以便把时间序列中蕴藏的信息充分显露出来，就是cc法(For one-dimensional time series by delay coordinate phase space reconstruction method extended to high-dimensional space, in order to fully reveal the information hidden in the time series, cc France)

这是一种整流电路，可以将相位相差120的三相交流电变换为直流，变化方法用到了电机控制中的坐标变换，SVPWM算法，方法比较新颖。(a kind of circuit which can convert three_phase AC voltage to DC voltge)

读取matlab 文件夹中所有的文件路径 包括子文件夹的文件路径(Read all matlab folder including subfolders file path file path)

有限差分法解泊松方程、拉普拉斯方程 定义边界后利用五点差分法求解(The five-point difference method for solving the Poisson equation)

DTW与MFCC相结合的语音特征提取算法，改进了MFCC的性能(Combination of DTW and the MFCC feature extraction algorithm for voice, improving the performance of MFCC)

说明：  matlab 常用命令 matlab 常用命令(frequently used commands commonly used commands matlab matlab)

说明：  灰色GM(1,1)和DGM源代码，功能齐全，各种显示内容均添加(Grey GM (1,1) source code, complete functions, various displays are added)

可以将信号很好的进行LMD分解，很好用，自己试试看(The signal can be well decomposed into LMD)

说明：  SLM算法的ccdf表示，用来降低OFDM系统中papr值。(SLM ccdf algorithm, used to reduce the OFDM system papr value.)
