Branch: CURRENT, Version: 2.5, Package name: gsl-2.5, Maintainer: david

The GNU Scientific Library (GSL) is a collection of routines for
numerical computing. The routines have been written from scratch in
C, and present a modern Applications Programming Interface (API) for C
programmers, allowing wrappers to be written for very high level
languages. The source code is distributed under the GNU General
Public License.

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
Updated gsl to 2.2.1.

* What is new in gsl-2.2.1:

** reverted gsl_linalg_cholesky_decomp to its previous behavior
   so it is backward compatible; new cholesky routine is

Log message:
Updated gsl to 2.2.

* What is new in gsl-2.2:

   eigensystems (Victor Zverovich)

   gsl_ran_multivariate_gaussian (Timothée Flutre)

** added functions to estimate the 1-norm reciprocal condition
   number for various matrix factorizations:
     * gsl_linalg_cholesky_rcond
     * gsl_linalg_QRPT_rcond

   iterative linear solver

   for Givens rotations

   api has changed; consequently the functions:
   are now deprecated and will be removed in a future release.
