C4.5算法 matlab实现的，感觉还可以，大家可以看看！(the implementation of C4.5 using matlab)

《MATLAB程序设计教程》电子教案,里面有PPT教案以及matlab源程序("MATLAB Programming Guide" electronic lesson plans, There are lesson plans and Matlab PPT source! !)

A movement of charge carriers due to the concentration gradient in a semiconductor is called process of diffusion. When charge carriers move, the current is constituted in a bar. This current due to diffusion is called diffusion curren

单摆的MATLAB仿真程序源代码，结果会输出单摆摆动画面。(Pendulum MATLAB simulation program source code, the result will be output pendulum swing screen.)

Forward Modeling 1D using matlab

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)

implementation of classification based on least square error method in MATLAB environment.

ofdm的标准源代码，国外人写的，相当好(ofdm standard source code, written by foreign people, very good)

：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)

张德丰matlab小波分析源代码，从信号时-频联合分析引入小波变换，将信号的多分辨率分析及Mallat算法作为全书的重点，并在此基础上，进一步阐述了双正交小波多分辨率分析、小波包多分辨率分析、提升小波应用，还讲述了小波分析在奇异性检测、去噪及数据压缩中的应用。(Zhang Defeng Matlab wavelet analysis of the source code from the signal- frequency joint analysis of the introduction of wavelet transform, multi-resolution analysis of the signal and Mallat algorithm as the focus of the book, and on this basis, further elaborated biorthogonal wavelet multi-resolution analysis wavelet packet multi-resolution analysis, the lifting wavelet applications, but also about the application of wavelet analysis in the singularity detection, de-noising and data compression.)
