给出了reliefF算法的matlab源代码，该算法用于处理目标属性为连续值的回归问题。是由relief算法拓展所得，可以处理多类别问题。(ReliefF algorithm matlab source code is given, and the algorithm is used for processing target attribute is continuous values of regression problems.By expanding income relief algorithm, can deal with many categories.)

Alamouti Code 2X1 16-Qam

In a series of papers in recent years new structures for coherent M-PSK (M-ary Phase Shift Keying) receivers were suggested. These include structures for carrier phase detectors for the carrier PLL (Phase Lock Loop), carrier PLL lock detectors, symbol timing error detectors, symbol synchronization PLL lock detectors, carrier and symbol PLL loop filters, and SNR (Signal to Noise Ratio) estimators

a simple implementation of the basic pso algorithm

The onset of the T wave is the beginning point of the T wave, it s the first negative or null sample preceeding the T peak. The offset of the T wave is the ending point of the T wave, it s the first positive or null sample following the T peak.

EM 算法是Dempster，Laind，Rubin于1977年提出的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 MLE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。(EM algorithm is a method for maximum likelihood estimation of parameters proposed by Dempster, Laind and Rubin in 1977. It can estimate parameters from incomplete data sets by MLE. It is a very simple and practical learning algorithm. This method can be widely used in dealing with the so-called incomplete data such as defective data, censored data and noisy data. Specifically, we can use EM algorithm to fill missing data in samples, find hidden variable values, estimate parameters in HMM, estimate parameters in finite mixed distribution, and so on. Unsupervised clustering and so on.)

matlab处理dat文件并进行绘图,但dat格式有所限制,可能需要自己修改一下(processing matlab dat file and drawing, but dat format restrictions, you may need their own again)

读取硬盘SMART值,很详细的源代码。很有参考学习的价值(read hard smart value)
