Re: wavelet

Wilfried,
you might also want to check the wavelet packages that are available
for "R":

- http://cran.r-project.org/src/contrib/Descriptions/waveslim.html
- http://cran.r-project.org/src/contrib/Descriptions/wavethresh.html
- http://www.maths.bris.ac.uk/~wavethresh/ (wavethresh 3 and 4-beta)
- http://rss.acs.unt.edu/Rdoc/library/wavelets/html/wt.filter.html
