The GNU Scientific Library 1.1.1 is now available at
ftp://ftp.gnu.org/gnu/gsl/gsl-1.1.1.tar.gz
and from mirrors worldwide -- see http://www.gnu.org/order/ftp.html
The md5 signature is,
4c7dc29e0812b045ef4d5c30d23f064a gsl-1.1.1.tar.gz
The GNU Scientific Library (GSL) is a collection of routines for
numerical computing in C. In addition to bug fixes this release
includes the following new features:
- The complete set of random number generators from the new 3rd
edition of Knuth's Art of Computer Programming (Carlo Perassi)
- Functions for generating combinations (Szymon Jaroszewicz)
- Divided differences and polynomial interpolation (Dan, Ho-Jin)
- A new incomplete Gamma function implementation with
improved convergence (Hans E. Plesser)
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 all the contributors who reported bugs and suggested
improvements.
-------------------------
* What is new in gsl-1.1.1:
** Fixes to histogram2d stat functions
** Added missing prototypes for complex LU determinant functions
** Improved error handling in multifit routines
** Added check to avoid division by zero for rank-deficient matrix in
multifit iteration
* What is new in gsl-1.1:
** The permutation module now includes a copy function
gsl_permutation_memcpy
** The implementation of gsl_sf_gamma_inc has been improved and now
avoids problems caused by internal singularities which occurred in the
series expansion for some combinations of parameters.
** IEEE comparisons of infinities and NaNs are tested during the
configure stage and the functions gsl_isnan, gsl_isinf and gsl_finite
are only compiled on platforms which support the necessary tests.
** The histogram routines now include a sum function,
gsl_histogram_sum for computing the total bin sum, and additional
statistics functions for 2d histograms.
** Internal error checking of user-defined functions has been improved
in the multiroots functions.
** Constants now include the Bohr Radius and Vacuum Permittivity.
** Range checking is now turned off when building the library, but is
still on by default when compiling user applications.
** A combinations directory has been added for generating combinations (n,k).
** The gamma function now returns exact values for integer arguments.
** Fixed bugs in gsl_sf_hyperg_1F1_int and gsl_sf_hyperg_1F1.
** Fixed internal error handling in gsl_sf_laguerre_n to allow
recovery from overflow.
** Several routines for handling divided difference polynomials have
been added to the poly/ directory.
** The interpolation routines now include polynomial interpolation,
based on divided-differences.
** Added new random number generators from Knuth's Seminumerical
Algorithms, 3rd Edition: borosh13, coveyou, fishman18, fishman20,
fishman2x, knuthran, knuthran2, lecuyer21, waterman14.
** Changed divisor in random number generator gfsr4 from 2^32-1 to
2^32 to prevent exact value of 1.0 from being returned, as specified
in the documentation.
