数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改 第八章(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which were modified some procedures of Chapter VIII)

matlab开发的蚁群算法。希望对你有用。(Matlab development ant colony algorithm. Hope to be useful to you.)

小波包分析提取振动信号中的特征频率，一个很有用的程序，数值分析的EULER法。( Wavelet packet analysis to extract vibration signal characteristic frequency, A very useful program, EULER numerical analysis method.)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.
