-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi i have put together functions to calculate the discrete wavelet transform in 1D (gsl_vector_double) and 2D (gsl_matrix_double). i have already implemented different wavelets (beylkin, coiflet, daubechies, haar). i have verified the output against paul addisons illustrated wavelet transform book and matlabs wavekit. the numerical output is the same (minus rounding/numerics) but note that the position of the T submatrices occuring at each levels is different in the book compared with the output of wavekit. the position of Th and Tv (the off-diagonal blocks are exchanged). the output of my implemetation is the same as in the book. is this something that could be included in gsl? if yes i would still need to write some tests (suggestions welcome) and documentation. the attached archive contains the code and illustrations for 1D and 2D. - -- Dr. Ivo Alxneit Laboratory for Solar Technology phone: +41 56 310 4092 CH-5232 Villigen fax: +41 56 310 2624 Paul Scherrer Institute http://solar.web.psi.ch Switzerland gnupg key: 0x515E30C7 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQFAS0kbAd7CE1FeMMcRAkuhAKCjXhtqWMzGaP5BkQGI+Ngv7CSn1wCeMUEm +1sbYaxt146BSNkwqjzJdmI= =08yf -----END PGP SIGNATURE-----
