E10_Distance_Protection

这是我在学习过程使用到的一些程序，希望对大家有所帮助!(This is what I used in the learning process some of the procedures, I hope all of you to help!)

function g=nonlineareq(x) Here is an example of nonlinear system that can be solved by using the Matlab command "fsolve" written in the file called "solution.m"

Device on off with eyes

300HZ 采样率下，50、60HZ陷波器及8HZ高通多项式实现。画出原始数据及滤波后数据并画出相应频谱(50/60HZ notch filter of the matlab program.Plot raw data and filtered data and corresponding Spectrum)

说明：  基于PID控制的永磁同步直线电机速度控制系统，输出速度能够较好的跟踪输入信号，控制效果比较理想(The speed control system of permanent magnet synchronous linear motor based on PID control can track the input signal better, and the control effect is ideal.)

The Levenberg–Marquardt Method

共7个matlab程序及两幅原始待处理图像，功能是图像压缩的实验，分别运用了DCT（1个程序），小波变换（5个程序）和小波包变换（1个）对图像进行压缩，各个程序的作用及程序注释已在程序中做了详细说明,程序均可直接运行(matlab program for image compression ,using DCT wave,wavelet,wavelet packet methods respectively .)

图像特征提取以及匹配，sift代码。可用于图片检索中，同比SURF，其算法可以较好的识别图像中文字(Image feature extraction and matching, sift the code. Can be used for image retrieval, up by SURF, the algorithm can better identify the image text)
