Basic Continuous and Discrete Time functions

单级倒立摆的PID控制 控制的目标是通过给小车底座施加一个力，使小车停留在预定的位置，并使杆不倒下 (lqr matlab)

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.

仿真实现了谱相关系数和谱相关函数，谱相关函数使用了频域计算法。谱相关函数做的比较好，但谱相关系数的计算个人感觉仍需后来者继续改进(Simulation spectral correlation coefficient and spectral correlation function, the calculation of the frequency domain using the spectral correlation function. Spectral correlation function do better, but the spectral correlation coefficient calculated personal feeling is still a latecomer to continue to improve)

应用于PET的蒙特卡罗仿真方面的资料，可以用来作为指导性文献(monte carlo simulation that is applied in the pet image reconstruction.)
