A GPG detached signature is available at: ftp://ftp.gnu.org/gnu/gsl/gsl-1.4.tar.gz.asc The md5 signature is, 7513e13525c073dc07e02cc4354294e2 gsl-1.4.tar.gz The GNU Scientific Library (GSL) is a collection of routines for numerical computing in C. This release is backwards compatible with previous 1.x releases. GSL now includes support for cumulative distribution functions (CDFs) contributed by Jason H. Stover. The full NEWS file entry is appended below. The 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 - ------------------------- * What is new in gsl-1.4: ** Added cumulative distribution functions and their inverses for the continuous random distributions including: gaussian, lognormal, gamma, beta, cauchy, laplace, chisq, exponential, gumbel, weibull, F-distribution, t-distribution, logistic, pareto and rayleigh. ** Added faster binomial random variates using the TPE rejection algorithm, in the function gsl_randist_binomial_tpe. ** Added new functions gsl_rng_fwrite and gsl_rnd_fread for storing the state of random number generators in a file. ** Added a new function gsl_combination_memcpy() ** Corrected values of electrical constants in CGS units. To take account of different electrical systems of units the values are now prefixed by GSL_CONST_MKSA (for the SI Metre, Kilogram, Second, Ampere system) or GSL_CONST_CGSM (for the Centimetre, Gram, Second, Magnetic system with the Gauss as the fundamental unit of magnetic field strength). The previous GSL_CONST_MKS and GSL_CONST_CGS prefixes have been removed, as have the permeability and permittivity constants in the CGS system since this uses different defining equations. ** Fixed bugs in the random number generators gsl_rng_fishman18, gsl_rng_fishman2x, and gsl_rng_knuthran2 which caused them to return incorrect results. Minor corrections were made to the parameters in the other Knuth generators borosh13, coveyou, fishman20, lecuyer21, and waterman14. ** Fixed a missing transpose bug in the gsl_linalg_QR_QRsolve and gsl_linalg_QRPT_QRsolve routines which were computing the solution to Q^T R x = b instead of Q R x = b. ** Fixed gsl_sf_gammainv to return zero instead of a domain error for arguments corresponding to singularities in gamma. ** Fixed a bug in the simplex minimization algorithm which caused it to fail to find the second highest point correctly when searching the set of simplex points. ** Fixed a bug in the conjugate gradient minimizers conjugate_pr, conjugate_fr and vector_bgfs which caused the search directions to be updated incorrectly. ** Fixed a bug in gsl_sf_psi_1_int(1) which caused it to return the incorrect sign for psi(1,1). ** Fixed the simulated annealing routine gsl_siman_solve to use the parameter iters_fixed_T for the number of iterations at fixed temperature instead of n_tries. ** Fixed a bug in gsl_combination_valid which caused it to return the incorrect status. ** Fixed a bug in gsl_permutation_canonical_to_linear which caused the output to always be zero, and the input permutation to be incorrectly replaced by the output. ** Fixed a bug is gsl_ran_discrete which could cause uninitialised data to be returned for some distributions. ** Fixed the dependencies for gsl_chebyshev.h to include gsl_math.h. ** Fixed a bug in gsl_complex_arccsc_real which caused it to return the incorrect sign for the imaginary part when -1<x<0. ** Fixed a bug in the QAWC Cauchy integration routine which could allow the singularity to fall on an interval boundary, leading to division by zero. ** Improved gsl_sf_gamma_inc_P(a,x) to avoid a domain error for x<<a when a>10. ** Improved the accuracy of gsl_sf_coupling_3j for large arguments. ** Improved the performance of gsl_sf_choose(m,n) by separating the calculations for small and large arguments. ** On platforms without IEEE comparisons gsl_{isnan,isinf,finite} will fall back to the system versions of isnan, isinf and finite if available. ** gsl_linalg_householder_hv now uses BLAS routines internally ** The script configure.in is now compatible with autoconf-2.50 and later. ** Reduced the memory usage of the multifit algorithms from MxM to MxN for large M by performing the QR decomposition of the Jacobian in-place. ** IEEE modes now use the C99 fenv.h functions when platform spectific functions are not available. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iEYEARECAAYFAj9BCWsACgkQbiFv7WQGnVyEywCfb6OY6qUTLNA+ErJlDviNU4xo SX8AnRcxOsTKAY57wA1ZdhCPJQ85vm4b =ewVo -----END PGP SIGNATURE----- ^ permalink raw reply [flat|nested] only message in thread
