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) 0.8 is released Date: Wed, 19 Dec 2001 13:20:00 -0000 Message-id: X-SW-Source: 2001/msg00172.html Dear GSL enthusiasts, I have just placed a new release snapshot of GSL (0.8) up for anonymous ftp access at ftp://sources.redhat.com/pub/gsl/ and it should soon also be available at the mirror sites. The home page is at http://sources.redhat.com/gsl/ Installation: GSL uses the standard GNU installation procedure. The release tarball (gsl-0.8.tar.gz) comes with an INSTALL file. There is a zip file (gsl-0_8.zip) which includes project files for compiling GSL with Microsoft Visual C++ (see the file msvc/README.txt for details). Packaging: There is an RPM file for gsl-0.8 on the ftp site. Debian also provides GSL packages. Documentation: GSL has an extensive manual. The info files are installed in the usual way. The ftp site has the reference manual in postscript format, and the web site has the reference manual in HTML format. Here are the recent entries in the NEWS file. * What is new in gsl-0.8: ** The build process now uses the latest libtool and automake ** The library should now compile with Microsoft Visual C++ ** Portable versions of the isinf, isnan and finite functions are available as gsl_isinf(x), gsl_isnan(x) and gsl_finite(x). ** The definitions of GSL_POSINF, GSL_NEGINF and GSL_NAN no longer cause divisions by zero during compilation. ** The gsl_interp_obj has been renamed to gsl_interp ** The poly_eval and pow_int functions have been moved from the specfunc directory to the poly and sys directories. ** The Chebyshev functions are now available as an independent module in their own directory. ** The error handling conventions have been unified across the library. This simplifies the use of the special functions. ** A full CBLAS implementation is now included for systems where ATLAS has not been installed. The CBLAS library can also be used independently of GSL. The organisation of the BLAS directories has been simplified. ** IEEE support for HPUX-11, NetBSD, Apple Darwin and OS/2 are now included. ** The library now includes implementations of log1p, expm1, hypot, acosh, asinh, atanh for platforms which do not provide them. ** The convention for alloc and set functions has changed so that they are orthogonal. After allocating an object it is now necessary to initialize it. ** There is a new module for estimating numerical derivatives of functions ** There is a new module for handling data with ntuples ** The histogram lookup functions are now optimized for the case of uniform bins, and include an inline binary search for speed. ** The Chebyschev coefficients for the QAWO algorithm are now precomputed in a table for efficiency, rather than being computed on the fly. ** There are several new sorting functions for selecting the k-th smallest or largest elements of a dataset. ** Iterator functions are now available for permutations, gsl_permutation_next and gsl_permutation_prev. ** The function gsl_complex_xy has been renamed gsl_complex_rect ** The API for simulated annealing has been changed to support search spaces in which the points cannot be represented as contiguous-memory data structures. gsl_siman_solve() now takes three extra arguments: a copy constructor, a copy function and a destructor, allowing gsl_siman_solve() to do its work with linked data structures. If all three of these function pointers are NULL, then the traditioanl approach of using malloc(), memcpy(), and free() with the element size is used.
