an error code of GSL_EDOM when x is out of range

* spline.c (gsl_spline_free): handle NULL argument in free
* interp.c (gsl_interp_free): handle NULL argument in free
* accel.c (gsl_interp_accel_free): handle NULL argument in free
2008-09-05 Brian Gough <bjg@network-theory.co.uk>
* gsl_interp.h (gsl_interp_accel_find): corrected condition for
x>=xa.
2008-07-03 Brian Gough <bjg@hp2.network-theory.co.uk>
* gsl_interp.h: added inline declarations
* accel.c: moved gsl_interp_accel_find to inline.c
* bsearch.h bsearch.c: removed, moved to inline.c
* Makefile.am (INCLUDES): use top_srcdir instead of top_builddir
2007-03-14 Brian Gough <bjg@network-theory.co.uk>
* interp.c (gsl_interp_init): added check for monotonically
increasing x
2005-12-24 Brian Gough <bjg@network-theory.co.uk>
* cspline.c (cspline_init_periodic): fix invalid memory access of
xa[3] for sys_size=2
2005-12-22 Brian Gough <bjg@network-theory.co.uk>
* test.c (test_cspline2): added extra test of cspline
(test_cspline3): added extra test of cspline
2004-11-28 Brian Gough <bjg@network-theory.co.uk>
* cspline.c (cspline_init): support case of degenerate x[i] values
(cspline_init_periodic): support case of degenerate x[i] values

2003-07-24 Brian Gough <bjg@network-theory.co.uk>
* gsl_interp.h: removed duplicate declaration of
gsl_interp_accel_find
Sat Apr 27 20:57:22 2002 Brian Gough <bjg@network-theory.co.uk>
* cspline.c (cspline_init_periodic): handle boundary effects
correctly
Sun Dec 2 22:48:23 2001 Brian Gough <bjg@network-theory.co.uk>
* poly.c: added polynomial interpolation based on divided
differences from Dan, Ho-Jin.
Tue Jul 3 12:10:53 2001 Brian Gough <bjg@network-theory.co.uk>
* interp.c (DISCARD_STATUS): discard error status values using a
macro for configurability
Sun Jul 1 21:41:27 2001 Brian Gough <bjg@network-theory.co.uk>
* cspline.c: added const to state in appropriate places
Tue Jun 26 11:57:55 2001 Brian Gough <bjg@network-theory.co.uk>
* spline.c: added missing #include <string.h> for memcpy
Mon Jun 25 19:58:45 2001 Brian Gough <bjg@network-theory.co.uk>
* standardized to gsl conventions, added high-level 'spline'
interface
Mon Apr 30 13:29:34 2001 Brian Gough <bjg@network-theory.co.uk>
* renamed gsl_interp_obj to gsl_interp
Mon Apr 23 10:29:51 2001 Brian Gough <bjg@network-theory.co.uk>
* unified error handling conventions to _e for error handling
functions and no suffix for plain functions, so _impl functions
are no longer needed.
* removed tests for EFAULT, since EFAULT should only apply to
invalid non-null pointers.
Tue Apr 11 19:56:25 2000 Brian Gough <bjg@network-theory.co.uk>
* cspline.c (cspline_calc_periodic): changed occurrence of gsl_la
name to new gsl_linalg prefix, gsl_linalg_solve_symm_cyc_tridiag
(cspline_calc_natural): ditto
Mon Aug 30 11:31:00 1999 Brian Gough <bjg@network-theory.co.uk>
* bsearch.c: made gsl_interp_bsearch (formerly interp_bsearch) an
exported function, since it is needed by the inline version of
gsl_interp_accel_find in gsl_interp.h
