牛顿拉夫逊潮流计算，对电网进行潮流计算，用matlab语言编写(power calculate)

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 )

对局部放电信号去噪的性能进行评价，RMSE值越接近于1，去噪效果越好(The performance of partial discharge signal denoising is evaluated, and the closer the RMSE value is to 1, the better the denoising effect is)
