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

说明：  地震偏移成像技术比较经典且易理解的资料，比较有用(Seismic migration imaging more classic and easy to understand information more useful)

可以对小系统进行暂态稳定分析,主要是功角稳定，以判别系统是否失稳(can analyze the transient stability of small system, mainly for rotor angle stability, to determin if the system is unstable)

自己写的一个计算空间时频分布的程序，魏格纳威尔分布原代码(Wrote a frequency distribution calculating space program, Wigner distribution of the original code Weir)

关于MATLAB的基本算法，涵盖数学计算的一些基本源程序(The basic algorithm of MATLAB, covering some basic math source)

找函数的零点位置， 返回的是零点的index。 被找的函数须是连续函数 (Find zero points index of a continous function)
