matlab gui程序，可以通过选择不同类型，在窗口中显示不同的图形显示内容(a matlab gui program, it can display five kind of pictures)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

这是关于数字水印的提取例程！经过调试，可以放心使用！(This is on the digital watermark extraction routines! After debugging, can be assured use!)

这是emd程序源码，里面已经对边缘效应进行了处理。可以用来处理非平稳信号(This is the EMD program source, which has been on the edge effects have been dealt with. Can be used to handle non-stationary signal)

Simultaneous perturbation stochastic approximation

笔者费了很大的经历找到的matlab实例资料，希望大家好好利用，绝对经典的好资料哦(Programming with vc for the sample program, which contains many of the author s experience, I hope you make good use of)

电机的各种启动方式，包括直接启动，串电阻启动，降压启动，还包括电机的制动方式(A variety of ways to start the motor, including direct start, series resistance started, the buck starts, including braking motor)
