matlab求解峭度值，峰峰值，方差，均方差，协方差，裕度等统计学特征-Matlab solution of kurtosis, peak peak value, variance, variance, covariance, margin and other statistical characteristics

本文提出一种基于频率切片小波变换和谱峭度的综合算法。首先对轴承端的振动信号时频分析，采用FFT、包络谱、频率切片小波变换对其频域性能进行分析，再求其峭度谱与对应包络谱，结合其时域、频域性能，综合分析轴承故障。-This paper presents a synthesis algorithm based on frequency slice wavelet transform and spectral kurtosis. Firstly, the time-frequency analysis
