Matlab小波变换对于奇异点的检测，原始信号是含有奇异点的信号，为确定该奇异点的时间，采用haar小波进行连续小波变换后，在对系数进行分析处理。-Matlab wavelet transform to singular point detection, the original signal is containing the singularity of the signal, to determine the singular point time, adopting haar wavelet to continuous wavelet transform, the coefficients in analysis processing.
