根据邻接矩阵，计算复杂网络中模块的聚类系数。(According to the adjacency matrix, the computational complexity of the network module clustering coefficients.)

A suitable algorithm suggested with wavelet compression for gray scale images based on one- and two-dimension combined hierarchical structure, in the sub-band which has been generated by the aid of several types of wavelet functions. It is shown that the using of combined based hierarchical structures allows us to reduce the calculations complexity of compression and decompression at constant values of compression coefficients

这是一些关于模式识别工具箱的源代码,和模式识别第二版配套使用，有很强的运用价值。(These are some original Matlab codes on pattern classification:pattern calssification toolbox)

比例积分型的GPC，由新的目标函数解出的控制率与常规PI控制有着一样的形式，这样就获得了一种具有PI结构的广义预测控制，而且其参数 、 有着明显的工程意义，整定原则基本类似于PID。(Proportional-integral-type GPC, the new objective function solution of the control rate with conventional PI control has the same form, so to obtain a PI structure with generalized predictive control, and its parameters, there is a clear sense of the project, setting basic principle is similar to PID.)
