说明：  bandlet图像处理工具箱，以及用其进行图像去噪的程序(bandlet Image Processing Toolbox, and use its procedures for image denoising)

(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at 10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.
