中文说明：本程序的主要目的是针对高斯混合模型的参数估计问题而编写的，采用的算法是EM算法。对均值、方差和权重的估计已经写成独立的函数，并且保存成.M文件，运行时，只需要运行main.m文件即可。附有样本数据，存放在电子表格中。
English Description：
The main purpose of this procedure is written for parameter estimation in Gaussian mixture models, EM algorithm is the algorithm used. For mean, variance and weights are estimated to have been written as an independent function, and save it into. M-files, the runtime and only need to run the main.m file. With sample data stored in a spreadsheet.
