Hello everyone:

I am trying to do a wavelet analysis using DWT. Is there anyway, I can do a 3Dplot for coefficients of DWT.
I have done 3Dplot for CWT.
Forgive me if it is dumb question.

Hi Dominic, you can certainly implement a 3D plot of the DWT coefficients. There is not a ready made option in MATLAB to do it like with the CWT, but it would be relatively easy to implement. The hardest part would be that you would need to get the right approximate spacing of the DWT coefficients if you were using a decimated DWT. If you are using the stationary wavelet transform, then obviously the spacing of the coefficients would not be a problem.
