说明：  用MATLAB函数进行非线性拟合，在VB中调用(MATLAB function with non-linear fitting, call in VB)

编程经验的总结，教导我们如何编写高效无错的优质代码，包括编码习惯以及程序检错等(Programming and experience to teach us how to write high-quality and efficient error-free code, including coding practices, and procedures for error detection, etc.)

matlab调用libsvm时数据归一化与反归一化之归一化程序 (matlab libsvm)

EM 算法是求参数极大似然估计的一种方法，它可以从非完整数据集中对参数进行估计，是一种非常简单实用的学习算法。这种方法可以广泛地应用于处理缺损数据、截尾数据以及带有噪声等所谓的不完全数据，可以具体来说，我们可以利用EM算法来填充样本中的缺失数据、发现隐藏变量的值、估计HMM中的参数、估计有限混合分布中的参数以及可以进行无监督聚类等等。(Expectation Maximization image segmentation Input: ima: grey color image k: Number of classes Output: mask: clasification image mask mu: vector of class means v: vector of class variances p: vector of class proportions )
