信号时频分析matlab软件，使用GUI界面，非常简单，可以分析信号的时频特性以及进行谱分析(Signal time-frequency analysis matlab software using the GUI interface is very simple, can analyze the signal characteristics as well as the time-frequency spectral analysis)

很详细，具体的说明了matlab软件的入门和基础，希望对大家有帮助(Very detailed and specific description of the entry and basic matlab software, we hope to help)

最小二乘法源代码 用于MATLAB编程，解决相关哈之问题(the yuafaima)

1）先利用文件Lorenz.m求解出Lorenz系统，并把其数组保存成名字为un.mat的文件。 2）直接运行文件Lorenz1.m 便可统计出Lorenz系统的轨道(a) first use of document Lorenz.m solved Lorenz system, and the preservation of its array of un.mat name into the paper. 2) Run the file directly Lorenz1.m Lorenz will be the statistics on the track)

Sunspot activity is cyclical, reaching a maximum about every 11 years. Let s confirm that. Here is a plot of a quantity called the Zurich sunspot relative number, which measures both number and size of sunspots. Astronomers have tabulated this number for almost 300 years.

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 )
