这是MATLAB 主要函数指令表（按功能分类）.(This is the main function of MATLAB command table (according to the functions of classification).)

如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )

适合初学者，光流，有主函数及图片，有mex以及路径添加(Suitable for beginners, optical flow, main functions and picture,)

简明的matlab 实用程序集合；可以快速地掌握这一工具进行实际应用(concise Matlab practical procedures set; Quickly grasp of the tools for practical application)

JFET Amplifier and Frequency Response Analysis

二维FDTD仿真soft source入射到有限区域边界后的传播，区域中间放置了一块pec，并且设定了ABC边界条件，可以自动生成关于Ez，Hx和Hy的.avi文件，播放脉冲动态传输。(Dimensional FDTD simulation soft source is incident to spread limited area boundary after placing a piece of the middle region pec, and set the ABC boundary conditions, can automatically generate .avi files on Ez, Hx and Hy, and play dynamic pulse transmission.)

1．产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通， 低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。 2.采集一段含有噪音的语音信号（可以录制含有噪音的信号，或者录制语音后再加进噪音信号），对其进行 采样和频谱分析，根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)

ID3决策树算法，实现不同条件下数据的分类(ID3 decision tree algorithm, the classification of data under different conditions)
