这是学习matlab的资料，还可以的，希望对大家有帮助。(This is a learning matlab information, but also hope to have everyone help.)

该算法为最小均方误差滤波，对输入信号进行滤波，输出滤波后的波形和误差(The least squares algorithm, the input signal is filtered, and the filtered output waveform error)

DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法。用于孤立词识别，DTW算法与HMM算法在训练阶段需要提供大量的语音数据，通过反复计算才能得到模型参数，而DTW算法的训练中几乎不需要额外的计算。所以在孤立词语音识别中，DTW算法仍然得到广泛的应用。 (DTW (Dynamic Time Warping, dynamic time warping) algorithm based on dynamic programming (DP) ideas, sounds of varying lengths to solve the template matching problem, is speech recognition appeared earlier, more classic kind of algorithm. For isolated word recognition, DTW algorithm and HMM algorithm in the training phase need to provide a large number of voice data, obtained by repeated calculations to model parameters, while the DTW algorithm is almost no additional training calculations. Therefore, in isolated word speech recognition, DTW algorithm is still widely used.)

In recent years, stepping with the popularization of smart phone and the development of mobile communication infrastructure, the conditions for ubiquitous computing society become more and more complete. In the vision of ubiquitous computing society, LBS (Location Based Service) that provides an added value to an unprecedented user experience has been paid a great deal of attention by mobile operators all over the world. As the core technology for LBS, various positioning systems have been studied extensively. For the outdoor environment GPS is mature and common. However, the performance of GPS in indoor environment is bad. Moreover, currently there is no technique whose accuracy and cost are appropriate for deployment in huge areas.

说明：  首先确定被评价对象的因素（指标）集和评价（等级）集；再分别确定各个因素的权重及它们的隶属度向量，获得模糊评判矩阵；最后把模糊评判矩阵与因素的权向量进行模糊运算并进行归一化，得到模糊综合评价结果(Firstly, the factor (index) set and the evaluation (grade) set of the evaluated object are determined; then the weight of each factor and their membership degree vectors are determined separately, and the fuzzy evaluation matrix is obtained; finally, the fuzzy evaluation matrix and the weight vector of the factor are fuzzily calculated and normalized, and the result of the fuzzy comprehensive evaluation is obtained.)
