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 libtool, autoconf and automake. The full NEWS file entry is appended below. The file details are: ftp://ftp.gnu.org/gnu/gsl/gsl-1.12.tar.gz (2.8 MB) ftp://ftp.gnu.org/gnu/gsl/gsl-1.12.tar.gz.sig (GPG signature) 3b5cba13f4b90e1473f693a5dc7efdcaae55fc46 (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-1.12: ** Upgraded to latest libtool, autoconf and automake (libtool-2.2.6, autoconf-2.63, automake-1.10.2) ** Improved the convergence of gsl_sf_gamma_inc_P for x/a ~=~ 1 and large x,a. Fixes problems with large arguments in cdf functions such as gsl_cdf_chisq_Pinv(x,nu) [bug 24704]. ** Fixed gsl_ran_gamma_knuth to handle the case of a >= UINT_MAX [bug #24897] ** Added gsl_bspline_eval_deriv to compute bspline derivatives (Rhys Ulerich) ** Added a faster simplex mininimser gsl_multimin_fminimizer_nmsimplex2 which is O(N) instead of O(N^2) [bug #24418] ** Improved the original chi-squared formula in gsl_monte_vegas to avoid catastrophic cancellation [bug #24510]. The previous formula could return incorrect or negative values for relative errors < 1e-8, which could occur when integrating very smooth functions. ** Added new auxiliary functions gsl_cheb_order, gsl_cheb_size, gsl_cheb_coeffs for Chebyshev series [bug #21830] ** Updated license of the reference manual to GNU FDL version 1.3. ** Fixed a bug where the gsl_isinf function would return +1 for -Inf on systems where isinf(-Inf) returns the non-standard value +1. [bug #24489] ** Added missing functions gsl_vector_complex_{isnonneg,add,sub,mul, div,scale,add_constant} and gsl_matrix_complex_float_isnonneg [bug #22478] ** Cross compilation should now work for x86 hosts. ** Fixed a bug in gsl_interp_accel_find() where values lying on the upper boundary between interpolation points could return the index from the lower side. [bug #24211] ** Fixed gsl_linalg_solve_cyc_tridiag so that its output respects the solution vector's stride. Previously the x_stride value was ignored causing the output to be incorrect for non-unit stride. [bug #24162] ** Corrected a bug in the series calculation of gsl_sf_ellint_Kcomp for k close to 1. [bug #24146] ** Extended gsl_linalg_QRPT_update to handle rectangular matrices. Corrected definition of the update formula in the manual for both gsl_linalg_QR_update and gsl_linalg_QRPT_update. ** Added routine gsl_linalg_cholesky_invert ** Fixed a bug the simplex algorithm which caused the second highest point to be incorrectly equal to the first when the first value was the highest, which could cause suboptimal convergence. [bug #23192] ** Fixed a problem with convergence for inverse gamma and chisq distribitions, gsl_cdf_gamma_{P,Q}inv and gsl_cdf_chisq_{P,Q}inv. [bug #23101] ** Improved the handling of constant regions in Vegas by eliminating spurious excess precision when computing box variances. ** Fixed a potential division by zero in gsl_monte_miser when the left/right weight factors decrease below 1. ** Fixed incorrect dimensions check in gsl_matrix_sub{row,column} -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iJwEAQECAAYFAklGpDgACgkQ9U2K2oCCH+oEbQP+I3P8PNPVhN1TvtNMOtu914Dg /ubr/7SHF1MekAwX2m9zEOwOHHQ41PMcIi73s8NL1XwZ9+xaG8ieXSRiH1SIoKJd oZ5KF8g7zV9XHhKudMmHJDud0aFinEKd4F1eydX84AZdoS7CN2t86U2g/tOKG/Co AxGnzqYnp7trzfqsVCKIRgQBEQIABgUCSUakOAAKCRBuIW/tZAadXKmbAJ9ibLHC 1wPvmgutT35isptRIqDPeQCdHsq7N+t2GhTlqpKwpqrEOvjMO30= =GaIA -----END PGP SIGNATURE----- ^ permalink raw reply [flat|nested] only message in thread
