构建了一个三层模型，并与雷克子波进行卷积，实现了地层正演模型(Construction of a three-tier model, and with Leike Zi wave convolution to achieve the stratigraphic forward model)

说明：  高等通信原理16_QAM symbol sequence of 2000 symbols and plot the constellation(Advanced Communication Theory 16_QAM symbol sequence of 2,000 symbols and plot the constellation)

this code is a particle filter code in 2 Dimension and integrated to extended kalman filter.

说明：  这是一个交叉验证函数, 用来选取训练集, 和测试集. 请放在matlab的工具箱中使用(this is a crossvalind. please use it in the matlab tools.)

Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices. Note: Directions of curvatures aren t calculated appropriately. Will post an updated version once this is implemented. Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.

说明：  MATLAB关于遗传算法的几个经典实例，需要的就下吧(MATLAB Genetic Algorithm on a few classic examples of needs on the next bar)

基于遗传算法的TSP算法，寻找最短的遍历N个城市的路径(TSP algorithm based on genetic algorithm to find the shortest path traversal N cities)

【转】协同过滤代码，用于推荐系统，包括基于项目和基于用户两种情况。实现基于用户和基于项目的协同过滤算法。 实验所用数据为MovieLens – a web-based movies recommender system with 43,000 users & over 3500 movies. 保存在ga.mat文件用，由于ga.test测试集过于庞大，全部用来计算的话耗时庞大，所以每次计算时随机选择部分，具体函数的使用请参照probar.m。我所得到的实验结果保存在results1-results8.mat里面。([Turn] collaborative filtering code for the recommended system, including project-based and user-based two cases.
