【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. User-based and project-based collaborative filtering algorithm. Experimental data for MovieLens- a web-based movies recommender system with 43,000 users & over 3500 movies. Saved in ga.mat file with Because ga.test test set is too large, all used to calculate the time-consuming massive, so every time The calculated random selection portion, the use of the specific function, please refer to probar.m. I obtained experimental results are saved inside results1-results8.mat.)

Matlab FieldII for windows.版本7.2(Windows that runs Matlab 7.10, 32 and 64 bits Field_II_PC7.zip )

Knapsack Problem. Russian version. Dynamic programming.

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

说明：  提供两个点坐标，可以利用本程序，计算两点距离，简单好用。(Coordinates of two points, you can use this procedure to calculate the distance to two points, easy-to-use.)

一个简单的GUI小程序，可以实现几种三维曲线的绘制与画等高线。(A simple GUI program, several three-dimensional curve drawing and painting contour.)

运用matlab混沌系统中的logistic映射的仿真； 运用keil对八路电子抢答器，有抢答和没抢答的设计，效果显示(Mapping of logistic chaotic systems using matlab simulation Using the keil to eight-way digital vies to answer first, vies to answer first and not vies to answer first the design, display effect )

matlab多种控制算法的源代码，包括时域响应的性能指标，由特征多项式构造胡尔维茨矩阵，根轨迹几何法设计串联超前控制器等(matlab variety of control algorithm source code, including the performance of the time domain response by the characteristic polynomial constructed Hurwitz matrix, root locus the geometric method designed series lead controller)
