说明：  原代码包括捷联惯导初始对准程序,实用性强,便于学习(chushiduizhun)

通过对基4快速傅里叶的介绍，使用matlab实现了基4快速傅里叶变化(Through the radix-4 Fast Fourier presentation, using matlab to achieve a base four fast Fourier transform)

it is useful for my research work

说明：  matlab读取iges文件程序，可导入特征数量、具体位置等多种信息。直接使用无需编辑。(Matlab read IGES file program, can import the number of features, specific location and other information. It can be used directly without editing.)

这五个源代码介绍了如何创建matlab GUI以及各种控件的放置调用(The five source code shows how to create a matlab GUI and the placement of the various controls calls )

matlab程序提取语音信号的基音频率、共振峰、能量、MFCC等特征参数。(The matlab program to extract the speech signal fundamental frequency, Gong Zhenfeng, energy, MFCC and other characteristic parameters.)

MATLAB执行ART2神经网络算法的执行程序和执行描述(MATLAB implementation of the implementation process and the implementation of ART2 neural network algorithm description)

脉冲编码调制程序，采用A律和u律，可在GUI中显示变换前后波形区别并播放声音。(A Pulse Code Modulation program based on A-law and u-law. Can display in the GUI waveform before-and-after difference and play the sound.)

这是一个异步电机基于磁场定向的矢量控制仿真模型，其中外环控制采用滑模变结构方式。(This is an asynchronous motor vector-based field-oriented control simulation model, which uses sliding mode outer loop control mode.)

说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)
