说明：  无传感器永磁同步电机matlab仿真 pid自适应 已调的还可以(Sensorless permanent magnet synchronous motor adaptive pid matlab simulation has been adjusted, they can still)

It is helpful in classifying the maturity stage of cotton.

计算Fisher的函数，根据Fisher可以计算出克罗美下界(Fisher s exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables[1]. The job of Fisher s exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn t found , or with bad computation. This function efficiently deals with Fisher s exact test with n x m contingency table. As for the function :)

灰色预测是一种对含有不确定因素的系统进行预测的方法。灰色预测通过鉴别系统因素之间发展趋势的相异程度，即进行关联分析，并对原始数据进行生成处理来寻找系统变动的规律，生成有较强规律性的数据序列，然后建立相应的微分方程模型。(Dissimilarity trends, namely, correlation analysis, and generate raw data processing system to find the law changes, generate a strong regularity of the data sequence, then the corresponding differential equation model.)
