stats 用于检验回归模型的统计量，有三个数值：相关系数r2、F值、与F对应的概率p.相关系数r2越接近1，说明回归方程越显著；F > F1-α（k，n-k-1）时拒绝H0，F越大，说明回归方程越显著；与F对应的概率p 时拒绝H0，回归模型成立.(stats for the test statistic of the regression model, there are three values: the correlation coefficient r2, F value, and F corresponds to the probability p. The correlation coefficient r2 more close to 1, note the more significant regression equation F> F1-α (k, nk-1) refused to H0, F the bigger shows the more significant regression equation F corresponds with the probability p refused H0, set up a regression model.)

扩展卡尔曼滤波和unsented卡尔曼滤MATLAB工具箱，很实用(Unsented extended Kalman filtering and Kalman filter MATLAB toolbox, very practical)

说明：  计算故障分类的每个属性的信息熵，选取最大的作为根节点(For fault classification information entropy of each attribute, select the largest as the root)

用于大气辐射传输模型modtran5的matlab程序，可读取编辑tape5文件，运行modtran以及读取运行结果。(It provides a set of functions (called “methods” in object-oriented programming terminology) that ease the handling of MODTRAN cases. These include methods to read the tape5 file format into a Mod5 class “instance” or “object”, alter the case instance described in the file, write the tape5 format back to a file, run MODTRAN on the case and read various results from MODTRAN output files back into Matlab.)
