This version includes new routines for wavelet decomposition, as well as bug-fixes. The full NEWS file entry is appended below.

Thanks to everyone who reported bugs and suggested improvements. - -- Brian Gough Network Theory Ltd, Commercial support for GSL --- http://www.network-theory.co.uk/gsl/ * What is new in gsl-1.6: ** Added a new wavelet directory, with 1-dimensional and 2-dimensional discrete wavelet transforms (Dr. Ivo Alxneit). ** Added support for LQ and P^T LQ decompositions. To find the QR decomposition of large systems (M>>N) use the LQ decomposition, solving the transpose of the original system. This allows more efficient memory access, and is useful for solving large least-squares problems (Dr. J. Wensch). ** Fixed a bug in the SYRK and HERK blas functions gsl_blas_{s,d,c,z}syrk and gsl_blas_{c,z}herk which caused invalid memory access for non-square matrices. ** Fixed a bug in gsl_swap_vectors which caused it to return incorrect results when swapping vectors with different strides. ** Corrected the error estimate for gsl_cheb_eval_n_err to use evaluation order instead of the approximation order. ** Improved the reliability of the gsl_sf_gamma_inc family of functions. ** Equal abscissae are now handled gracefully in the cspline and periodic cspline interpolations. ** Removed potential cancellation error in calculation of uniform histogram ranges. ** Improved numerical stability of integration for akima and cspline interpolation. ** Differential equation solvers now handle error codes returned from user-defined functions. ** Improved error estimates in ode-initval solvers, and provide exact derivatives on output. Added new semi-implicit ode-initval solver, gsl_odeiv_step_rk2simp. (T.Keskitalo) ** Added missing function definition for gsl_sf_psi_1. ** Fixed the function gsl_sf_expint_Ei_scaled to call gsl_sf_expint_Ei_scaled_e instead of gsl_sf_expint_Ei_e. ** Added cumulative distribution function for exponential power distribution (Dr.G.Bottazzi). ** The functions gsl_cdf_beta_P and gsl_cdf_beta_Q now return consistent results of 0 or 1 for out of range values, x<0 and x>1, rather than 0 for left and right tails simultaneously. ** The Jacobi eigensolvers gsl_eigen_jacobi and gsl_eigen_jacobi_invert have new implementations from Golub and Van Loan. ** The standard output and standard error streams are now flushed by the default error handler before the program aborts, in order to ensure that error messages are properly displayed on some platforms. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFB3CINbiFv7WQGnVwRAlHvAJwJQuLYCoejpnEH3AWF3OVwXU8mggCcDTLa D3EmaBsJnWUwZwZioA7et2Y= =sayi -----END PGP SIGNATURE-----
