三相级联H桥的研究和应用，希望能够对大家有所帮助，能和大家多交流(Research and Application of the three-phase cascade H-bridge, hoping to be helpful to everyone, and everyone can have more exchanges)

　蔡勒（Zeller）公式：是一个计算星期的公式。 　　随便给一个日期，就能用这个公式推算出是星期几。(Zeller (Zeller) formula: It is a formula for calculating week. Casual to a date, can be calculated using this formula out of the week.)

该程序主要说明直扩系统抑制正弦干扰方面的有效性。绘出不同幅度的正弦干扰信号及无干扰时的误码率.( This procedure mainly showed that expands the system to suppress the sine disturbance aspect straight the validity. Draws the different scope the sine unwanted signal and does not have when the disturbance error rate. )

In mathematics, the method of steepest descent or stationary phase method or saddle-point method is an extension of Laplace s method for approximating an integral, where one deforms a contour integral in the complex plane to pass near a stationary point (saddle point), in roughly the direction of steepest descent or stationary phase.

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 )
