fit_mix_gaussian - fit parameters for a mixed-gaussian distribution using EM algorithm format: [u,sig,t,iter] = fit_mix_gaussian( X,M ) input: X - input samples, Nx1 vector M - number of gaussians which are assumed to compose the distribution output: u - fitted mean for each gaussian sig - fitted standard deviation for each gaussian t - probability of each gaussian in the complete distribution iter- number of iterations done by the function

主要是用来K均值聚类，K值按照自己的需要设置并将聚类结果保存到相应目录下的excel文档中(Mainly used K-means clustering, K value is set according to their needs and clustering results are saved to the appropriate directory under the excel document)
