Matlab中的电弧电路编程，45KB，个人觉得还是很有用的。(Arc circuit in Matlab programming, 45KB, personally think it is very useful.)

中大数计的matlab的ppt,数学建模竞赛资料(The large numbers of dollars matlabppt)

说明：  最大类间方差法又称otus方法，是日本学者大津展之在最小二乘法原理基础上提出来的，其本质是一种阐值分割方法。 (Otsu method, also known as otus method, Otsu, Japan scholars in the development of the least squares method based on the principle put forward by its very nature is a kind of illustrates the value of segmentation.)

层数N对光子晶体带隙的影响，不同的介质层数N，即不同的周期数,传输矩阵也不同，光子晶体的反射率和透射率也不同。(Influence of layers N bandgap of photonic crystals)

实现加权最小二乘拟合，经典的系统辨识方法，很管用(Achieve a weighted least-squares fitting, classical system identification methods, it is useful)
