模式识别的重要工具箱，共同学习公共进步。(Pattern recognition toolbox, useful for all of us hope!)

Fourier coherence This program calculates the fourier coherence of a signal using cpsd function of matlab. Input and output are explained in file.

本程序基于matlab开发，作用是做回归分析及逐步回归分析(Regression analysis and stepwise regression)

完全极坐标的内点法最优潮流程序，通用版，所有节点可用。(OPF program completely polar coordinates interior point method, the generic version, all nodes are available.)

比较经典格拉姆施密特QR正交分解的matlab源程序(Comparison of the classical Gram Schmidt QR orthogonal decomposition matlab source)

Lempel_Ziv信源编解码 含测试数据(Lempel_Ziv_Coder/Decoder test_data included)

这个例子示出了充放电时的超级电容器的模式。该电路示出了与电池超级电容器的一个简单的杂交。超级电容器被连接到降压/升压转换器和电池连接到升压转换器。电池的功率由一个速率限制器块，因此瞬态功率由超级电容器供给到DC总线限制。(This example shows the supercapacitor model during charge and discharge. The circuit illustrates a simple hybridization of a supercapacitor with a battery. The supercapacitor is connected to a Buck/Boost converter and the battery is connected to a Boost converter. Power of the battery is limited by a rate limiter block, therefore the transient power is supplied to the DC bus by the supercapacitor.)

Finite Element for Total Variation Minimization

这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)
