这是从国外网站下载的Nonlinear dynamical factor analysis Matlab 源代码(This is the website from outside of the Nonlinear dynamical factor analysis Matlab source code)

matlab实现各种经典回归算法，如最小二乘，ridge，lasso，elastic net等等，以及各种回归算法应用实例。(Many classic regression methods such as least squares, ridge, lasso and elastic net and so on. In addition, some application examples are here indetails.)

基于欧几里得距离的聚类分析，未来线路预测,分析误差,阐述了负荷预测的应用研究。( Clustering analysis based on Euclidean distance, Future line prediction, error analysis, It describes the application of load forecasting.)

MATLAB三维绘制图，可以实现三维曲面图的旋转动画；用于文献汇报等。(MATLAB three-dimensional sketch, animation can rotate a three-dimensional surface plot for reports and other literature.)

利用离散点生成规则格网DEM，并利用MatLab生成的.dll来实现显示规则格网（三维）(Discrete point generating regular grid DEM, and use MatLab generated. Dll to the show rules grid (three-dimensional))

欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)

说明：  若锗中含有一定数量的杂质元素Sb，试根据要求分析杂质浓度与电离度以及电离温度之间的关系： （1）当Sb浓度分别为 和 时，计算杂质99％，90％和50％电离时的温度各为多少？ （2）根据一定杂质类型和杂质浓度，画出电离度和温度的关系图线，并确定半导体处于强电离区（电离度>90％）的温度范围。 设计要求：（1）具有友好输入输出界面； （2）调整输入数据，得出相应结果，并进行分析。 (If the germanium containing a certain number of impurity elements Sb, test analysis in accordance with the requirements of impurity concentration and ionization degree, as well as the relationship between the ionization temperature: (1) When the Sb concentration and time were calculated 99 percent of impurities, 90 and 50 ionization When the temperature of each number? (2) according to certain types of impurities and impurity concentration, ionization degree and temperature to draw the relationship between the graph lines, and to determine the semiconductor in a strong ionization zone (ionization degree)

matlab的实验报告，有雅可比迭代，最小二乘法和复化辛普森公式。(matlab experimental reports, Jacobi iteration, the least square method and complex formula of Simpson.)

说明：  matlab的中文帮助，对于学习matlab比较有用！(Chinese matlab help matlab more useful for learning!)
