压缩传感的一种恢复算法-omp,对初学压缩传感的有很大帮助(A recovery algorithm for compressed sensing-omp, compressed sensing for beginners of great help)

合式公式的判断，根据输入的公式判断是否是合式公式，数理逻辑(Well-formed formulas of the judge, according to the formula to determine whether the input is a well-formed formulas, mathematical logic)

说明：  这是SIFT算法在匹配遥感方面的一个应用，实现自动匹配识别功能(This is the SIFT algorithm to match an application of remote sensing, automatic matching recognition)

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.)
