GSL provides a large collection of routines for numerical computing in C. This is a maintenance release, which fixes reported bugs and upgrades the build system to the latest autoconf and automake. The full NEWS file entry is appended below. The file details are: ftp://ftp.gnu.org/gnu/gsl/gsl-1.13.tar.gz (2.9 MB) ftp://ftp.gnu.org/gnu/gsl/gsl-1.13.tar.gz.sig (GPG signature) 02db78b9583bc7b2a577da6f45f5dd9f23ef737e (sha1 checksum) The GSL project homepage is http://www.gnu.org/software/gsl/ GSL is free software distributed under the GNU General Public License. Thanks to everyone who reported bugs and contributed improvements. Brian Gough (GSL Maintainer) ====================================================================== * What is new in gsl-1.13: ** Upgraded to latest autoconf and automake (autoconf-2.64, automake-1.11) ** Fixed the rk4 and bspline allocators to avoid invalid free() calls under out of memory conditions. [bug #27194, #27236] ** Fixed a bug in gsl_multimin_fminimizer_nmsimplex2 where the center and size of the simplex were not updated on contract-by-best steps, causing failures in convergence. [bug #27180] ** Added new functions to set MISER and VEGAS Monte Carlo integration parameters, and to examine VEGAS chi-squared value and intermediate results. ** Added the function gsl_bspline_greville_abscissa to compute Greville abscissae for B-splines. ** The cumulative distribution functions gsl_cdf_gumbel1_{P,Q} should now handle a larger range of parameters without underflow and overflow. ** The header file gsl_const_cgs.h no longer defines values for electromagnetic units. Applications should use gsl_const_cgsm.h instead to obtain the values in the CGS-Magnetic system. The previous values for these units given in gsl_const_cgs.h were ill-defined as the type of CGS electromagnetic system was unspecified (the values were a mixture of CGS units with the Ampere of the MSKA system). The affected constants are GSL_CONST_CGS_BOHR_MAGNETON, GSL_CONST_CGS_ELECTRON_CHARGE, GSL_CONST_CGS_ELECTRON_MAGNETIC_MOMENT, GSL_CONST_CGS_FARADAY, GSL_CONST_CGS_GAUSS, GSL_CONST_CGS_NUCLEAR_MAGNETON, GSL_CONST_CGS_PROTON_MAGNETIC_MOMENT, and GSL_CONST_CGS_ROENTGEN. ** The Pochhammer functions gsl_sf_poch(a,x) and gsl_sf_lnpoch(a,x) now handle the special cases where a and a+x are zero or negative integers. ** The confluent hypergeometric function gsl_sf_hyperg_U (a,b,x) now handles some cases where x=0. The case where 1+a-b is a negative integer no longer returns an error [bug #22859] and the incorrect termination of the series in certain cases is fixed [bug #26706]. ** Added a new function gsl_poly_eval_derivs to evaluate a polynomial and its derivatives simultaneously. ** Added a new univariate minimisation algorithm gsl_min_fminimizer_quad_golden which is a variant of Brent's algorithm with safeguarded step-length adjustment. ** Added a new Nelder-Mead minimiser gsl_multimin_fminimizer_nmsimplex2rand which uses a randomly oriented simplex rather than one fixed on the coordinate axes [bug #25077] ** The texinfo file now uses the dircategory "Software libraries" from the Free Software Directory, as recommended in the Texinfo manual. ** The function gsl_ran_exponential now includes zero in its output range. [bug #25039] ** All functions for freeing allocated memory now accept a NULL pointer, following the standard C convention for free(). [bug #25319] ** The function gsl_sum_levin_u_accel now handles the special case c_0 + 0 + 0 + 0 + .... that occurs when summing power series c_n*x^n with x=0. [bug #26807] ** The functions gsl_linalg_LU_solve, gsl_linalg_LU_svx, gsl_linalg_LU_refine, gsl_linalg_LU_invert and their complex equivalents now return an error for singular matrices. ** The multifit LMDER hybrid solvers now check the return code of the user-supplied function in the gsl_multifit_fdfsolver_set method. [bug #26871] ** Improved the implementation of gsl_ran_discrete_preproc to avoid internal errors due to inconsistencies from excess precision on some platforms. [bug #26502] ** Corrected gsl_sf_hyperg_2F1(a,b,c,x) to not give a domain error in the case where c is a negative integer and the series terminates with a finite result. ** The C99 inline keyword is now supported, in addition to the previously supported GNU-style inline. ** Modified gsl_poly_complex_solve_cubic and gsl_poly_solve_cubic to avoid returning NaNs in cases where excess precision causes a change in the number of roots. ** Fixed incorrect length check in gsl_blas_drotm. [bug #26503] ** Fixed gsl_odeiv_step_gear2 to restore y on step failure ** gsl_odeiv_evolve_apply now restores the correct value of t on step failures [bug #26255]. ** Using make install prefix=DIR now puts correct paths in package config files gsl-config and gsl.pc ** Modified gsl_monte_vegas to work around pow() function inaccuracies on MinGW [bug #25413]. ** Increased the number of terms in gsl_sf_mathieu_a and gsl_sf_mathieu_b to improve convergence in difficult regions [bug #25075] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iJwEAQECAAYFAkqmebEACgkQ9U2K2oCCH+pjsQQAzr6z0BY8z/dM3tVHTczbEXo5 +q5Ayil/v7KpeThc58Sy7XeWoLgf0BcgccoZ97rt7YWr4sB1e9Um5N7vIZO2bNo3 4lb9wBr4kL1V/Ldd9QoTC6aIWeXYmVBQ3tGXtsOKl3LufW/QKQLjrBnMihRsF9uk UH0a97c5JxhQjuSoiso= =klpC -----END PGP SIGNATURE----- ^ permalink raw reply [flat|nested] only message in thread
