混合高斯分布的em算法，e步和m步，输出各参数值(mixture of gaussian,em)

this is a source code written in the matlab format for the teaching learning optimization algorithm.

//给定整数n，产生所有[2n]上的匹配（matching） //将其视为一个所有块大小均为2的集合分拆 //以a_i表示其第i个元素所在的集合号 //输出格式为 a1 a2 a3 ... //满足 //a_{i+1} <= max { a1,a2,...a_i } + 1 (//a given integer n, have all [2n] on the matching (matching)// will be considered as an all pieces are two sets of a split// a_i said in its i elements of a collection of lies// output format for a1 a2 a3 ...// meet// a_ i (a))
