Hi, I would like to plot a wavelet transform in 3-D, with scale, time and amplitude as 3 axes. First, to apply the WT, which function would you use? Second, how would you plot the result? P.S. I have Signal Processing and Wavelet toolboxes. Thank you in advance. _____________________________________ Do you know a company who employs DSP engineers?
