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

Thanks to everyone who reported bugs and suggested
improvements.

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_rngfwrite and
gslrnd_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_CONSTMKS and
GSLCONST_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_rngfishman2x, and gslrng_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_sfpsi1_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_permutationcanonicalto_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_sfgammainc_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.
