用于算法的 迭代，方便初学者直接查找。更可以灵活运用(For iteration, easy for beginners to find directly. More flexibility to use)

将实验采集的人生理信号进行处理，提取心音信号，对心音信号进行时域和频域分析(The experiments were collected physiological signal processing, extraction of heart sound signals, heart sound signals in time domain and frequency domain analysis)

用matlab写的模板匹配算法，用于基于轮廓提取的多边形近似匹配算法(Matlab write template matching algorithm for approximate matching algorithm based on contour extraction polygon)

使用matlab计算微小球形颗粒在介质中的散射系数(Calculation of small spherical particles in the medium mie coefficients)

说明：  复杂背景下利用聚类决策的弱小目标提取方法(Complex decision-making context of weak clustering method for object extraction)

基于EMD的直流电机换向电流提取程序。内含用LEM公司的霍尔传感器实测的微型直流电动机启动时的电流信号（真实的数据和大家分享），分别用小波滤波和EMD消噪，并用EMD提取直流分量、高频换向电流，对研究电机间接测速、启动特性测试很有帮助，对电机故障诊断也有帮助。(EMD-based DC motor commutation current extraction procedures. LEM s included with Hall sensors measured miniature DC motor start-up current signals (real data and to share), respectively, with wavelet filtering and EMD de-noising and extracted DC component with EMD, a high-frequency current commutation of indirect research motor speed, starting characteristics testing is helpful, for motor fault diagnosis can also help.)
