Parameter identification for a single-degree-of-freedom system using autoregressive moving average model: Application to cutting system

PLS-DA法是将定量偏最小二乘法用于判别分析的一种策略，其基本思想是将已知类别样本的浓度阵分别设为0、1（对两类用PLS1方法而言），或-1、0、1（对三类用PLS1方法而言），或01、10（对两类用PLS2方法而言），或001、010、100（对三类用PLS2方法而言），多类问题依次类推，再通过定量PLS方法建立模型。(PLS- DA method is to use quantitative partial least squares discriminant analysis of a kind of strategy, the basic idea is to known categories the concentration of the sample matrix is set to 0, 1 (for two types of PLS1 method), or 1, 0, 1 (for three types of PLS1 method), or 01, 10 (for two types of PLS2 method), or 001, 010, 100 (for three PLS2 method), many questions so on, through quantitative PLS method to establish model.)

基于MATLAB 对数据进行处理 加密解密(MATLAB-based encryption and decryption of data processing)

　　非晶态硅Forouhi-Bloomer模型参数拟合计算 　　半导体材料对光的吸收作用用k表示。材料的k一般都会随着入射光的波长的改变而改变。其变化规律因材料而异，但是对于同一类型的材料常可以用一种模型来表示。但是对于特定的材料，其模型参数的确定常的通过曲线拟合的方法得到的。 　　题目： 　　对于非晶态的硅，其K满足如下模型： 　　 　　其中A、B、C为系数，且均大于零，并满足4C-B2>0 Eg为禁带宽度，值为1.3 ev , E为能量。 　　现已知一组E对应的K值，通过曲线拟合的方法求出A,B,C。(Curve fitting)
