说明：  基于小波的图像压缩的MATLAB程序，可以运行，我试验过(Wavelet-based image compression MATLAB program, you can run, I tried)

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

常规潮流计算，采用牛拉法、直角坐标系，并有IEEE6、14、30、57、118、300节点数据和计算结果(Conventional flow calculation, using cow Rafah, Cartesian coordinates, and IEEE6, 14,30,57,118,300 node data and calculated results)

一个关于matlab工程应用的PPT，希望能对用matlab进行工程分析的人有帮助！(Matlab project on the application of PPT, with the hope that it can carry out engineering analysis matlab help people!)
