   Hi, does anyone know where I could find code (preferably in C) to
perform wavelet analysis AND synthesis (reconstruction) on a time
series.  I have been trying to code this myself but the reconstructions
aren't correct, so I have a bug somewhere.  Actually code that
just does wavelet analysis would be helpful also.

   Any help greatly appreciated.

The following article was posted to a newsgroup (possibly this one) a
few weeks ago.
My guess is that the code is in Fortran rather than C.  I am not sure
this will
solve your problem (viz. synthesis), but maybe it will help.

========================cut here==================================
Preprints and software are available by anonymous ftp from the
Yale Mathematics Department computer ceres.math.yale.edu[130.132.23.22],
in pub/wavelets and pub/software.

epic is pyramid wavelet coder. (For source code, see question 3 in part one).

Bill Press of Harvard/CfA has made some things available for anonymous
ftp on site is 128.103.40.79, directory /pub. There is a short TeX
article on wavelet theory (wavelet.tex, to be included in a future
edition of Numerical Recipes), some sample wavelet code (wavelet.f, in
FORTRAN - sigh), and a beta version of an astronomical image
compression program which he is currently developing (FITS format data
files only, in fitspress08.tar.Z).

Check out the latest issue of Dr. Dobbs Journal. It contains wavelet code in C
Their code is usually also available on CompuServe.
Hope this helps,
Jurgen
