主要介绍了遗传算法在matlab中实现方式并利用了英国一所大学所用遗传工具箱。(ntroduces genetic algorithm implementation in matlab using a British university used genetic toolbox.)

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.)

The model of a discrete system with variable step size calculation is given in the file vsfunc.m. Considered S-function simulates the signal delay device. The delay time is determined by the input signal.
