DPCM_DCT_m

matlab codes to determine normalized correlation, psnr and log of an image

龙格库塔算法Runge-Kutta，包括二阶到四阶的MATLAB程序。(Runge-Kutta MATLAB 123456)

在matlab环境下的系统小波的电力系统谐波分析的M程序(In the matlab environment system of the wavelet power system harmonic analysis M program)

读取视频文件的函数。比matlab工具箱中的mmreader更好用。(Read the video file functions. Than matlab toolbox mmreader better use.)

时频窗口选取并计算，有效选择时频窗口。对初学者有用(yields a window of length N with a given shape)

说明：  基于bp神经网络的遥感图像的分类和识别的MATLAB实现(Bp neural network-based remote sensing image classification and recognition of the MATLAB implementation)

说明：  这里有2组图，“1000.0.05”这一组是运行结果比较好的一组图，但是当时修改了时间间隔而没有改坐标说明，所以db1000.0.05.fig这幅图的坐标说明后来做了人工改正（应该是“time(0～250ms分成5000组,步长0.05ms”）。(Reuters, "1000.0.05" This group is running a relatively good results Reuters. But then amended the time interval and not changed coordinates Note So db1000.0.05.fig site map coordinates statement later became the artificial correction (should be "ti me (0 ~ 250ms group into 5000, 0.05 Step ").)

快速计算离散分数阶Fourier的方法，不多介绍啦。(Disfrft)

it contains report ,matlab codes for PAPR ofdm reduction techniques like SLM,PTS methods.all are working.
