关于数学模型的一些简单介绍以及如何进行数学建模(Mathematical Modeling)

说明：  内容：运用PM算法识别空间目标。程序中附有注释，可改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: The use of PM space target recognition algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

齿轮接触疲劳强度分析程序，机械设计中使用。(Gear contact fatigue strength analysis program, used in mechanical design。 )

加入邻域信息的空间模糊c均值聚类算法的代码。(Join neighborhood information, spatial fuzzy c-means clustering algorithm code.)

说明：  建立并绘制任意信号的模糊函数。已在巴克码，线性调频，脉冲信号中测试过。(This program estimates and plots the ambiguity function for any signals. I have tested it for the Barker code, chirp signal, pulse signal. for good results the length of the input vector (Ut)should be more than 7. Example- a rectangular pulse should be described as[1 1 1 1 1 1 1]. Please, give your suggestions. it is made with the help of "xcorr" function (Author: R. Losada) in MATLAB and Ilia Iliev from TU-Sofia )

说明：  Voltage distribution in a triangle

这是关于没分燃烧的udf，同学们可以借鉴，利用的是二阶矩模型(this is a combustion udf,which was using the second ju model ,you can use it for referance)

小小的最近邻算法，希望能够对大家有所帮助(Tiny nearest neighbor algorithm , hoping to be helpful to everyone)

电力系统负荷分析，并带有同步调相机，欢迎下载(Power system load analysis, with synchronous condenser, welcome to download)

一本用于matlab系统仿真的电子书籍，对初学者有很大的帮助。(A used in matlab simulation of electronic books, has a great help for beginners. )
