I'm looking for Matlab code for ploting scaling function and wavelet
for Daubechies D2, D3
and Coiflet

Great, do you have more about the wavelets for DSPs?

Regarding the missing files "reverse" and "image_resize", they seem to be in Gabriel's other toolboxes on Matlab Central: "Toolbox signal" and "Toolbox Misc". HTH!

I tried to use MATLAB7.0 to perform 1D wavelet transform mentioned in lecture 1, but an error message was displayed as below:

??? Undefined command/function 'reverse'.

Error in ==> perform_wavelet_transform>aconv at 761
fflip = reverse(f);

Error in ==> perform_wavelet_transform>DownDyadLo at 714
d = aconv(qmf,x);

Error in ==> perform_wavelet_transform>FWT_PO at 468
beta = DownDyadLo(beta,qmf) ;

Error in ==> perform_wavelet_transform at 123
y = FWT_PO(x,Jmin,qmf);

When I tried to perform 2D wavelet transform in lecture 1. The error message was shown as :
??? Undefined command/function 'image_resize'.

Error in ==> load_image at 253
M = image_resize(M,n,n);

Why do all these problems occur? Are some files missing?

Thanks in advance.

This set of numerical experiments complements "A Wavelet Tour" nicely. The examples follow the book. The writing avoids theory and sticks to application. It is also a good standalone wavelets introduction: skip the math and see wavelets in action.
