说明: 滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

weightpercent
Returns weighted percentiles of a sample given the weight vector w
% The idea is to give more emphasis in some examples of data as compared to
% others by giving more weight. For example, we could give lower weights to
% the outliers.
% The motivation to write this function is to compute percentiles for Monte
% Carlos simulations where some simulations are very bad (in terms of goodness
% of fit between simulated and actual value) than the others and to give
% the lower weights based on some goodness of fit criteria.(Returns weighted percentiles of a sample given the weight vector w The idea is to give more emphasis in some examples of data as compared to others by giving more weight.
