Version 1.16 of the GNU Scientific Library (GSL) is now available. GSL
provides a large collection of routines for numerical computing in C.
This release includes significant new features and bug fixes:
- nonlinear least squares fitting can now compute the Jacobian
numerically with finite differences if the user doesn't wish to specify
an analytic Jacobian
- support for robust linear regression
- Spearman correlation coefficient
- numerous bug fixes
The full NEWS file entry is appended below.
The file details for this release are:

Thanks to everyone who reported bugs and contributed improvements.
* What is new in gsl-1.16:
** fixed error in gsl_rng_fwrite where uninitialized padding
bytes were being written (bug #39104)
** fixed error in gsl_block_alloc where padding bytes were not
properly initialized (bugs #39101,#39102,#39103)
** fixed error in ntuple/test.c where padding bytes were not
properly initialized (bug #39105)
** fixed triangle selection bug in gsl_sf_coupling_6j_e and
gsl_sf_coupling_9j_e (bugs #39466 and #29606) (HÃ¥kan Johansson and
** added higher level wrapper routine gsl_multifit_fdfsolver_driver
** converted gsl_multifit_linear_residuals to use dgemv to improve
efficiency (bug #39153)
** added functions gsl_stats_spearman and gsl_sort_vector2 to compute
Spearman rank correlation
** added function gsl_poly_dd_hermite_init for Hermite interpolation
** Added support for robust linear least squares
** Added function gsl_linalg_SV_leverage for computing statistical
leverages from SVD decomposition
** Added support for approximating the Jacobian of nonlinear least
squares fits using forward finite differences
** Extended gsl_sf_coupling_3j to allow larger range and to handle
the special case (ja jb jc; 0 0 0)=0 when ja+jb+jc is odd
** Fixed gsl_sf_mathieu_se_array to return zero when the order is zero
** Fixed overflow in gsl_sf_lncosh for large negative x (x<-354).
** Improved gsl_ran_negative_binomial_pdf to avoid underflow/overflow
for large arguments.
** Multisets now allow k strictly greater than n.
** Fixed gsl_matrix_complex_fwrite/fread failure for noncontiguous
matrices (Matthias Sitte).
