用matlab便的支持向量机预测方面的界面，希望对大家有用。(using Matlab would support vector machine interface projections, we hope that the right useful.)

求复杂网络的节点度的分布和平均节点的度，输入邻接矩阵，输出度的分布(Complicated network node degree distribution and the average node degree, input adjacency matrix, the output distribution of the degree of)

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.

说明：  用于matlab用牛顿迭代法解方程，这个在数值计算中是很重要的(Matlab by Newton' s iterative method for solving equations, this in numerical calculation is very important to)

无线通信之MIMO系统的天线分集技术编程(The MIMO diversity programming system of the wireless communication)

OFDM系统级的仿真，里面涉及到卷积编码，交织，qpsk调制等(OFDM system-level simulation, which relates to convolutional coding, interleaving, qpsk modulation)

说明：  正态总体参数的检验,调用ztest和ttest函数(Inspection normal population parameters)
