4 prevent singularity falling on interval boundary
6 Mon Apr 29 20:05:56 2002 Brian Gough <bjg@network-theory.co.uk>

9 replacing endpoints center+half_length by b and center-half_length
12 Mon Jul 30 17:46:42 2001 Brian Gough <bjg@network-theory.co.uk>
14 * test.c (main): reduced tolerance on qagiu(f455) smooth elist
17 Mon Jul 2 15:42:41 2001 Brian Gough <bjg@network-theory.co.uk>
19 * util.c: split out some static functions into separate files
21 Tue Apr 17 22:11:28 2001 Brian Gough <bjg@network-theory.co.uk>
23 * qc25f.c (qc25f): need GSL_ERROR_VOID because function does not
26 Mon Apr 16 20:09:09 2001 Brian Gough <bjg@network-theory.co.uk>
28 * qc25f.c (qc25f): removed unnecessary variables, replaced use of
31 * qmomof.c (gsl_integration_qawo_table_set_length): removed
32 unnecessary duplicate variable declaration for i
34 Mon Jan 22 12:35:05 2001 Brian Gough <bjg@network-theory.co.uk>
36 * qmomof.c: moments are now precomputed in a read-only table
37 instead of being computed on the fly (cached)
39 Fri Dec 8 19:45:52 2000 Brian Gough <bjg@network-theory.co.uk>
41 * reorganized, made internal functions static
43 Thu Nov 16 19:45:19 2000 Brian Gough <bjg@network-theory.co.uk>
45 * qag_impl.c (gsl_integration_qag_impl): replace use of volatile
46 with the macro GSL_COERCE_DBL
48 Wed May 31 19:35:57 2000 Brian Gough <bjg@network-theory.co.uk>
50 * test.c (main): increased tolerances on some results to allow
51 tests to pass with other compilers
53 Mon May 15 14:21:00 2000 Brian Gough <bjg@network-theory.co.uk>
55 * test.c (main): increased one test limit slightly to allow for
58 Wed Feb 23 14:35:31 2000 Brian Gough <bjg@network-theory.co.uk>
60 * qpsrt.c (qpsrt): changed ordering of while conditions to avoid
61 segmentation faults due to accessing values before testing end of
62 loop condition. Thanks to Brett Viren
63 <bviren@superk.physics.sunysb.edu> for pointing this out.
65 * qelg.c (qelg): changed update of nres from the original quadpack
66 so that uninitialized elements of the res3la array are never
69 * test.c (main): eliminate small memory leak from test
71 Mon Feb 14 13:45:04 2000 Brian Gough <bjg@network-theory.co.uk>
73 * qk.c: renamed function qk to gsl_integration_qk since it is
76 * err.c: made internal function rescale_err static, only used in
79 Mon Jul 12 11:37:55 1999 Brian Gough <bjg@network-theory.co.uk>
81 * qawc_impl.c (gsl_integration_qawc_impl): removed, no longer
82 necessary since everything goes into qawc.c
84 Fri Apr 2 20:57:09 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
86 * qelg.c (qelg): removed debugging code
88 * qpsrt.c (qpsrt): removed debugging code
90 Thu Mar 11 15:15:46 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
92 * qags_impl.c (gsl_integration_qags_impl): removed dependency in
93 quadrature function calls by introducing dummy variables resabs1
96 Wed Mar 10 19:05:41 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
98 * added integrators QAGI, QAGIU, QAGIL for infinite and
101 1999-01-01 Mark Galassi <rosalia@cygnus.com>
103 * integration.c: replaced strings.h with string.h, which is the
106 Sat Nov 21 12:43:03 1998 Brian Gough <bjg@vvv.lanl.gov>
108 * Makefile.am (libgslintegration_a_SOURCES): eliminated local
109 max.h in favor of global GSL_MAX
111 * added missing gsl_math.h headers for new GSL_DBL_EPSILON macros
113 Tue Nov 17 17:16:51 1998 Brian Gough <bjg@vvv.lanl.gov>
115 * added #include <config.h> to all top-level source files
117 Fri Jun 12 22:30:21 1998 Brian Gough <bjg@vvv.lanl.gov>
119 * qage_impl.c: started using volatile (selectively) to enforce
120 strict IEEE behavior for the branches where it matters. I was
121 going to use gcc's -ffloat-store option but it didn't work for me.
122 Using volatile is not really a complete solution but is probably
123 close enough for all practical purposes (also it doesn't degrade
124 the performance as much as -ffloat-store would).
126 Sat May 30 15:40:51 1998 Brian Gough <bjg@vvv.lanl.gov>
128 * test.c (main): basic tests of qage are now complete
130 * qage_impl.c (gsl_integration_qage_impl): fixed serious bug for
131 index i, which was incremented at the end of the do loop and
132 give an extra undefined entry in the result list!
