基于欧式距离的KNN分类方法,本代码只适用于将数据分为三类。类数更多或更少需要简单的调整。(KNN classification method based on Euclidean distance)

人口灰色预测模型可以在数学建模中应用，预测人口数量的变化，灰常灰常灰常有用。(gm grey prediction may not be perfect but it s useful u know. used in mathmatical test for population prediction. very very useful)

使用了核技巧的费舍尔判别法应用程序，有效提高费舍尔效果。(Use of nuclear techniques application Fisher Criterion, effectively improve the Fisher effect.)

求解高斯积分点及其权重的计算程序。程序计算一维、二维、三维的高斯点及其权值，用于数值积分。原来写的一个有限元程序，所以有能力给6节点的三角形单元的积分点(A program for solving Gauss integral points and their weights is presented.Program calculates the gauss points for 1-D,2-D,3-D along with their weights for use in numerical integration. Originally written for a Finite Element Program so has the capability to give integration points for a 6-node Triangle element)
