Matlab的编程例题，关于BP神经网络的PID温度控制(Matlab programming examples on BP neural network PID temperature control)

说明：  进行基于最大最小方法和K均值结合的分类方法 并画出具体的分类情况，对二维数组具有鲁棒性。(Based on max-min method and combination of K-means classification method and draw a specific classification of two-dimensional array with robustness.)

3-level inverter for power electronics applications

Maximum Likelihood Decoding

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.
