基于MATLAB／SIMULINK交流调速系统的仿真研究(Based on MATLAB/SIMULINK simulation of AC Speed Control System)

主成分做排名的matlab代码，运用主成分分析计算教练排名得分的方法。( Principal component rankings do matlab code, using principal component analysis method to calculate the coach ranking score.)

基于MATLAB编写的代码，采用小波阈值降噪的方法对采集的光谱信号进行滤波处理。可自行设定阈值，实现不同的滤波效果。(Based on the code written in MATLAB, using wavelet threshold noise reduction method for filtering spectrum signal acquisition process. You can set the threshold to achieve different filter effects.)

提取声音信号的MFCC特征参数，然后进行匹配，有训练语音，也有测试语音，测试信号既有训练过的，也有没训练过的，都可以识别(The MFCC feature parameters of sound signal are extracted and matched. There are both trained and tested voices. The tested signals can be recognized by both trained and untrained voices.)

这个包，包含了好多比较经典的MATLAB程序 这是本人收藏多年的成果，现在上传给大家分享(This package contains a lot of comparison classic MATLAB program which is the outcome of my collection for many years, and now upload to the U.S. to share)

本文章中介绍了行业软件ansys的基础知识，基本操作以及一些高级的应用，对于刚接触ansys的人是很好的入门材料(This article describes the basics of the industry software ansys, the basic operation and some advanced applications, for people new to ansys is a good introductory material)

MATLAB实现圆环阵方向图，方位角为九十度，以及最大峰值旁瓣电平(MATLAB realize the circle array pattern, an azimuth of ninety degrees, and the maximum peak side-lobe level)

关于非线性离散系统辨识！还不错的东西，自己课设的东西！(Identification of nonlinear discrete systems!)

这是一本有关MATLAB的参考书，适合于使用MATLAB或正在打算使用MATLAB的读者。本书另辟蹊径可以借助或不借助MATLAB随带的文档资料让读者自学MATLAB。 作为编程语言和可视化工具,MATLAB具有丰富的一系列功能,可解决工程、科学计算和数学学科中许多问题。本书的基本目的是通过向读者展示如何有效地使用这些功能来帮助读者增强工作能力。由于MATLAB交互式的性质,书中内容以举例方式来描述。在读者阅读本书的同时, 这些例子可以通过运行MATLAB而再现。 (This is a reference book on MATLAB, suitable for the use of MATLAB or is intended to use MATLAB readers. Another way this book can make use of, or without the aid of MATLAB documentation that came with the reader learning MATLAB. As a programming language and visualization tools, MATLAB has a rich range of functions, solve engineering, scientific computing and mathematics disciplines, many problems. The basic purpose of this book by showing the reader how to effectively use these features to help readers enhance the ability to work. Since MATLAB interactive nature of the book by way of example to describe the content. The reader to read this book at the same time, these examples by running the MATLAB and reproduction.)

一个有趣的人走动程序，很有趣的。。。。。。(One interesting people walking program, very interesting. . . . . .)
