支持向量机的非线性回归预测，得到回归方程的参数，可进行预测(Nonlinear regression predicting support vector machine regression equation obtained parameters can be predicted)

MATLAB实现潮流计算的程序基本使用牛顿拉夫逊法进行计算(Matlab load flow)

压缩感知中调幅信号的稀疏字典训练及稀疏表示，包含KSVD算法，OMP算法(Sparse dictionary training and sparse representation of amplitude modulation signal in compressed sensing, including KSVD algorithm, OMP algorithm)

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.
