From mboxrd@z Thu Jan 1 00:00:00 1970 From: Brian Gough To: gsl-announce@sources.redhat.com Cc: gsl-discuss@sources.redhat.com Subject: GNU Scientific Library (GSL) 0.9.4 is released - 5th Beta Test Release Date: Mon, 29 Oct 2001 09:24:00 -0000 Message-id: X-SW-Source: 2001/msg00010.html Dear GSL enthusiasts, I have placed a new release snapshot of GSL (0.9.4) up for anonymous ftp access. The source code is available from the following locations, USA: ftp://mirrors.rcn.net/pub/sourceware/gsl/ UK: ftp://ftp.mirror.ac.uk/sites/sourceware.cygnus.com/pub/gsl/ The project home page is at http://sources.redhat.com/gsl/ This release fixes all bugs reported recently and improves the consistency of the library. In particular, the multidimensional minimisation ("multimin") functions now use the same interface as the "multiroots" and "multifit" functions. Please report any problems to gsl-discuss@sources.redhat.com. Here are the recent entries in the NEWS file. * What is new in gsl-0.9.4: * Reorganized the multmin functions to use the same interface as the other iterative solvers. * Added histogram _alloc functions for consistency, in addition to the existing _calloc functions. * Renamed all the gsl_multimin functions to be consistent with the rest of the library. An underscore has been removed from _minimizer in all the function names. * Renamed the function gsl_sf_coulomb_CL_list to gsl_sf_coulomb_CL_array * A bug in the multimin functions where the function parameters (params) were omitted has been fixed. * A bug in the nonlinear minimization routines has been fixed, which could prevent the algorithms from converging. Additional tests from the NIST reference datasets have been added and these now agree with MINPACK. * All the physical constants and conversion factors are now defined as real numbers to avoid potential problems with integer arithmetic. * The ODE evolution routines now allow for negative step sizes, and integrating backwards as well as forwards. * The implicit Burlisch-Stoer ODE algorithm 'bsimp' now detects singularities and forces a reduction in step size, preventing runaway instabilities. * Fixed a bug in the ODE evolution function gsl_odeiv_evolve_apply which could cause an erroneous value to be returned if the step size is reduced on the last step.
