一维EM算法MATLAB实现，两分支高斯混合模型，均值和方差都不相同。(one dimensino EM algorithm implemented by MATLAB. Estimate the mean and variance of Gaussian Mixture Model with two branches.)

说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法，设 计一带阻滤波器，并将设计的滤波器应用到一混和正弦信号，通过测试检验，该滤波器可以很好地消除50Hz的工 频干扰。(】To prevent the biomedical signals from being disturbed by 50Hz noise easily，the paper designs a bandstop digital filter by procedure and FDATool method．The filter is tested by a blended 81ne wave experimentally and the result shows that the filter can cancel the 50Hz noise very well．)

由方波代替了SPWM，实现了SPWM电机调速(Replaced by a square-wave SPWM, motor speed to achieve the SPWM)

matlab下编写的基于哈尔小波的分解与重构函数，有详细注释(matlab prepared Haar wavelet-based decomposition and reconstruction of the function, there are detailed notes)

朱邦芬只保留电子-声子互作用算符 对角项，把非对角项作为微扰处理； 原则上，不同的电子态对应于不同的晶格平衡位置；通常计算固体的振动性质时，假定电子处于基态。 (Zhu bonfim retain only electronic- phonon interaction diagonal operator, the diagonal of the non-perturbative as processing in principle, different electronic states corresponding to different lattice equilibrium position usually calculate the vibration of the solid nature, it is assumed that e in the ground state.)
