小波去噪的分解与重构示例，里面附带数据文件(Wavelet Denoising sample decomposition and reconstruction, which attached to data files)

Matlab循环定义变量，可以定义任意多个变量，matlab字符串数组的创建(Matlab loop defined variables, you can define any number of variables, matlab creation of an array of strings)

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.)
