Low rank revealing matrix QR decomposition method

Albert-László Barabási与Réka Albert在1999年的论文中提出了一个模型来解释复杂网络的无标度特性，称为BA模型。这个模型基于两个假设： 增长模式：不少现实网络是不断扩大不断增长而来的，例如互联网中新网页的诞生，人际网络中新朋友的加入，新的论文的发表，航空网络中新机场的建造等等。 优先连接模式：新的节点在加入时会倾向于与有更多连接的节点相连，例如新网页一般会有到知名的网络站点的连接，新加入社群的人会想与社群中的知名人士结识，新的论文倾向于引用已被广泛引用的著名文献，新机场会优先考虑建立与大机场之间的航线等等。 (Albert-László Barabási with Réka Albert in the 1999 paper proposed a model to explain the complex networks of scale-free property, known as the BA model. This model is based on two assumptions: Growth pattern: a lot of real network is expanding growing from, for example, the birth of the Internet BEIJING, page, new friends to join the network of people, a new paper published aviation network in the new airport construction and so on. Priority connection mode: a new node upon accession will tend to connect to the node connected to, for example, a new page will generally have a connection to the well-known networking sites, and the new Community will want with the community s well-known get to know the new paper preference is to use well-known literature has been widely cited, the new airport will give priority to create and airport routes.)

基于粗细定位相结合的车牌识别方法，有别于一般的车牌识别算法，有兴趣的可以研究一下哈～(Based on the combination of coarse and fine positioning plate recognition, license plate recognition algorithm is different from the general, interested can look at Ha ~)

用MATLAB实现的RSA。界面友好，可加密任意长度字符串。(MATLAB RSA. Friendly interface, encryption arbitrary length of the string.)

OFDM simulation for transmission and reciever

是一本英文版的关于matlab在金融领域应用的书籍，对于需要分析统计海量数据的人有一定帮助哦(This text describes a set of MATLAB functions that implement a host of econometric estimation methods. )

说明：  卡尔曼滤波器是用前一个估计值和最近一个观察数据估计信号的值，他是用状态方程和递推的方法进行估计，本例用来追踪一个5阶的FIR不确定的滤波器系数。(Kalman filter is to use the previous estimate and the most recent observation data to estimate the value of the signal, he is using the state equation and recursive estimation methods, in this case is used to track a 5-order FIR filter coefficients of uncertainty.)

水平竖直线交点就是输入些水平线段和竖直线段的坐标（文件输入） 然后输出几个交点(The level of vertical lines is the intersection of some level of input the coordinates of line segments and vertical segments (file type) and then the output of several intersection)

这是一个高斯分类算法的程序，有多种多元分类算法。(This is a gaussian classification algorithm of the program, a variety of multi-classification algorithm.)
