学习matlab的好的课件，可以下载研究一下(Matlab' s a good learning courseware, you can download study)

matlab/simulink simpowersystems (Three-phase_asynchronous_motor_reversal)

Matlab仿真程序，介绍了数据的程序结构、运用和算法设计。(Matlab simulation program, introduced procedures for data structure, application and algorithm design.)

数字信号处理的直接对象是数字信号，处理的方式是数值运算的方式，它涉及到的内容非常丰富和广泛，它是应用最快、成效最显著的新学科之一，做为信息专业的专业基础课，需要掌握其基本理论和基本的分析方法，通过理论和实践、原理和应用结合让学生掌握知识。而matlab是集数学计算、图形处理和程序语言设计于一体的软件，通过matlab来实现数字信号处理的有关表达，最终实现课程设计的目的。(Direct object of digital signal processing digital signal processing approach is the way value operation, which involves the contents of the very rich and extensive, it is the fastest application, the effectiveness of the most significant one of the new disciplines, as information on professional expertise basic course, need to understand the basic theory and basic methods of analysis, theory and practice, theory and application integration to enable students to acquire knowledge. The matlab is a mathematical calculation, graphics processing and program design in one of the software, through matlab to implement digital signal processing of the expression, and ultimately the purpose of course design.)

现代通信系统使用MATLAB一书中第二章，书的作者是刘树堂(Modern communication systems using MATLAB, a book chapter, book the author is LIU Shu-tang)

1. 构造含噪音的振动信号 faultysignal_with_noise， 2. 利用小波变换 Wavelet transform去噪，小波包 Wavelet packet transform 变换去噪， 3. 把两种去噪后的信号，分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed. 2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising, 3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)

PCA with K-nn classifier(for pictures)

独立主成分分析的工具箱，是模式识别，成分分析，线性判别的重要手段。(independent Principal Component Analysis Toolbox, pattern recognition, component analysis and linear discriminant an important means.)

simulation of ultrasonic cavitation. to use with RP function file in order to plot bubble radius time development.

this code in used in neural network mlp with back propagation training algorithm and geradian descends algorithm for optimization.in some of this codes I used full propagation algorithm or mlp one layer or two layer with different activation function.this code can be use for prediction or control system by useing neural networks.
