用mfcc函数实现语音信号的特征提取，对提取数据进行分析 模式识别的一道例题(With MFCC function realization of speech signals to extract feature extraction and analysis of the data and pattern recognition of a sample )

The primary objective of the QRD-M detector is to identify the candidate list. The QRD-M algorithm is a breadth-first tree search. It views all the branches it will ever consider for a given stage of the detection tree and then rejects all but the Mi best nodes at the i-th detection stage before continuing on to the next stage.

此段程序描述了电偶极子在静态的情况下的电场、电势分布图。 比较简单注重在一些基本语句的使用(This procedure describes the electric dipole in the case of static electric fields, electric potential distribution maps. Relatively simple focus on the use of some of the basic statement)

极性LMS自适应滤波器，实现信号的自适应滤波作用(Polarity LMS adaptive filter, adaptive filter to achieve the role of signal)

说明：  基于灰色系统的预测，内涵数列预测和较难实现的包络预测(Prediction based on gray system, meaning the number of columns predictable and difficult to achieve the envelope prediction)
