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 )

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

说明：  巴特沃斯滤波的算法，希望对大家有所帮助，自己写的。(Butterworth filter algorithm, we want to help, his writing.)

帮助实现N阶自适应滤波器的滤波原理，通过读入一组信号并对其进行去噪的处理，通过频谱图看出其良好的滤波效果从而发现N阶自适应滤波器的优点(N-order adaptive filter to help achieve the principle of filtering, by reading into a signal and its de-noising processing, through the spectrum to see their good filtering effect to discover the advantages of adaptive filter of order N)

常见使用函数，利用积分求图形面积，函数可移植性强，有助于matlab学习，并也可直接利用。(By using matlab integral area)

Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec
