多种数学建模方法算法代码，每年数学建模代码(A variety of mathematical modeling algorithm code, annual mathematical modeling code)

铣削加工动力学单自由度半离散方法,求解铣削加工稳定性叶瓣图，不同于两自由度(The single degree of freedom (sdof) semi-discrete method for milling dynamics is used to solve the stability profile of milling process, which is different from that of two degrees of freedom)

这是一个BPSK调制和产生噪声的一段程序，顺有仿真结果。(This is a BPSK modulation and noise section of the procedure, Shun has simulation results.)

这个是用阶跃风速、风轮、传动系统以及转速控制器的模型，来观测风力发电机的阶跃相应(This step is to use the wind speed, wind turbines, transmission system and the model of the speed controller to measure wind generators step accordingly)

几个数据拟合的例子，比较简单，供大家学习。(Several examples of data fitting, relatively simple for everyone to learn.)

功率谱函数的MATLAB代码，内含加窗函数代码，并附带解释标注。(Power spectrum function)

【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.)
