This version is a bug-fix release, and is backwards compatible with previous 1.x releases. The full NEWS file entry is appended below. The GSL project home page is at http://www.gnu.org/software/gsl/ GSL is free software distributed under the GNU General Public License. Thanks to everyone who reported bugs and suggested improvements. - -- Brian Gough Network Theory Ltd, Publishing Free Software Manuals --- http://www.network-theory.co.uk/ - ------------------------ * What is new in gsl-1.5: ** Multifit routines now handle iterations where |f| is already minimised to zero, without division by zero. ** Fixed the singular value tolerance test in the multifit covariance calculation from < to <= to match the original MINPACK code. ** The macro HAVE_INLINE is now tested with #ifdef instead of #if as in versions prior to 1.4, to match the documentation, and the macro GSL_RANGE_CHECK_OFF now works correctly. An alternative macro GSL_RANGE_CHECK={0,1} can be used to control range-checking. ** Fixed a potential array overflow in gsl_ran_landau. ** Fixed a small discrepancy in the tolerance calculation of the one-dimensional brent minimiser. ** Numerical derivatives should now be calculated using the gsl_deriv_forward, gsl_deriv_central and gsl_deriv_backward functions, which accept a step-size argument in addition to the position x. The original gsl_diff functions (without the step-size) are deprecated. ** Corrected documentation for gsl_ran_hypergeometric_pdf() ** The tridiagonal matrix solvers gsl_linalg_solve_symm_tridiag, gsl_linalg_solve_tridiag, gsl_linalg_solve_symm_cyc_tridiag, gsl_linalg_solve_cyc_tridiag now use the GSL_ERROR macro to report errors, instead of simply returning an error code. The arguments to these functions must now use exact lengths with no additional elements. For cyclic systems all vectors must be of length N, for tridiagonal systems the offdiagonal elements must be of length N-1. ** The singular value decomposition routines gsl_linalg_SV_decomp and gsl_linalg_SV_decomp_mod now handle the SVD of a column vector (N=1, arbitrary M), which can occur in linear fitting. ** Restored missing header files gsl_const_mks.h and gsl_const_cgs.h. The incorrect values of the electrical units for gsl_const_cgs (VACUUM_PERMEABILITY and VACUUM_PERMITTIVITY) have been removed. ** Fixed gsl_linalg_SV_decomp() to avoid an infinite loop when computing the SVD of matrices containing Inf and Nan. ** Fixed gsl_linalg_balance_columns() to avoid an infinite loop when rescaling matrices containing Inf and NaN. ** Fixed header file <gsl/gsl_sf_log.h> to include declarations for error codes in inline versions of gsl_sf_log functions ** Fixed header file <gsl/gsl_const.h> to include new MKSA and CGSM header files. ** Added Stefan-Boltzmann constant and Thomson cross section to physical constants -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iEYEARECAAYFAkDpbl0ACgkQbiFv7WQGnVwP8gCfSv6p+yaNKT/O4Cg2oNrJilIp aj4An2ZRGGtV0+IHKvO2N9g/mqAhTpCk =OECa -----END PGP SIGNATURE----- ^ permalink raw reply [flat|nested] only message in thread
