代码说明：

说明：此函数用于研究Mallet算法及滤波器设计此函数用于消噪处理分解的高频系数采用db9较好,即它的消失矩较大分解的有用信号小波高频系数基本趋于零对于噪声信号高频分解系数很大，便于阈值消噪处理(this function for research Mallet filter algorithm design and function for Denoising decomposition of high-frequency coefficients Terminal better that it's vanishing moments larger decomposition of useful signal, high-frequency coefficients tends to zero for high-frequency signal noise decomposition coefficient great ease threshold Denoising)
