代码说明：

  给定小波母函数,要求做连续小波变换，变换结果以图像形式给出（尺度－位移），说明并在图像上标出信号有哪几个成分。(For a given mother wavelet function, required to do continuous wavelet transform, transform results are given in the form of images (scale- displacement), indicating that the signal in the image on the marked which of several components.)
