基于standford大学cioffi教授的经典算法，计算有线信道的无限冲击响应滤波器系数。(Based on algorithm proposed by Prof. Cioffi, calculate the optimal IIR coefficients for cable channel.)

涵盖四种绘制三维图的方法，适合初学者，供参考(this zip consists of four methods for drawing 3D maps)

Filtering using Weiner filter

自治系统Poincare映射的计算方法，附有程序以及算例。运行庞加莱里面的“zhixing.m”文件即可。(Autonomous system Poincare mapping method of calculation with procedures and examples are given. Run Poincaré inside zhixing.m files.)

说明：  用matlab实现的fp树。目的是发现频繁项集，但是本代码只是实现了fp树(Fp tree with a matlab implementation. Aim is to discover frequent itemsets, but only realized the fp tree code)

说明：  求取大型稀疏矩阵的特征根和特征向量，适用于matlab6.1以上的环境(strike a large sparse matrix eigenvalue and eigenvalues above applies to the environment matlab6.1)
