说明：  利用小波变换极大值，重建源信号。包含主程序和三段子功能函数，使用小波变换进行六级分解，求出模极大值，并利用这些极大值重建源信号。
(Using the wavelet transform maximum and reconstruction of source signals.Contains the main program and three jokes functions, six levels of decomposition using the wavelet transform and modulus maxima, and take advantage of these great value reconstruction of source signals.)
