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.

i found this one on math work site hope it is helpful

使用simulink对高阶大时滞系统的模糊控制仿真，分别对使用模糊控制器前后进行对比，性能有较大的提高(fuzzy controller simulink)

用simulink的实现的 非常难找的系统的封装与发送回主程序的方法(Simulink realization is very difficult to find the package and sent back to the main program )
