对有类别监督的数据进行先行判别分析用于降维 数据为结构体类型，返回数据也是降维后的结构体类型。如(a.X a.y)a.X是带有类别的数据，a.y是类别信息(Synopsis: model = lda(data) model = lda(data,new_dim) Description: This function is implementation of Linear Discriminant Analysis. The goal is to train the linear transform which maximizes ratio between between-class and within-class scatter matrix of projected data.)

Matlab toolbox for data analysis

聚类重要步骤，利用数据之间的相似度自适应确定类别数(decide adaptive number of classes using similarity)

说明：  在进行矩阵求逆等计算时遇到矩阵条件数较大导致病态时，常用的各种解决病态方程方法(In the calculation of matrix inversion, when the number of matrix conditions is large, which leads to ill condition, various common methods to solve ill condition equation are used)

说明：  BP分类算法，实现多分类的任务，准确率高，耗时少(BP classification algorithm can realize multi-classification task with high accuracy and less time consuming|.)

说明：  自己写的一段kalman滤波,非常基础,加入了一致性分析(Himself wrote a kalman filter, very basic, joined the consistency analysis)
