2003-01-12 Brian Gough <brian.gough@network-theory.co.uk>
* qawc.c (gsl_integration_qawc): fixed bisection condition to
prevent singularity falling on interval boundary
Mon Apr 29 20:05:56 2002 Brian Gough <bjg@network-theory.co.uk>
* qcheb.c (gsl_integration_qcheb): avoid loss of precision by
replacing endpoints center+half_length by b and center-half_length
by a
Mon Jul 30 17:46:42 2001 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): reduced tolerance on qagiu(f455) smooth elist
test slightly
Mon Jul 2 15:42:41 2001 Brian Gough <bjg@network-theory.co.uk>
* util.c: split out some static functions into separate files
Tue Apr 17 22:11:28 2001 Brian Gough <bjg@network-theory.co.uk>
* qc25f.c (qc25f): need GSL_ERROR_VOID because function does not
return value
Mon Apr 16 20:09:09 2001 Brian Gough <bjg@network-theory.co.uk>
* qc25f.c (qc25f): removed unnecessary variables, replaced use of
abort by GSL_ERROR
* qmomof.c (gsl_integration_qawo_table_set_length): removed
unnecessary duplicate variable declaration for i
Mon Jan 22 12:35:05 2001 Brian Gough <bjg@network-theory.co.uk>
* qmomof.c: moments are now precomputed in a read-only table
instead of being computed on the fly (cached)
Fri Dec 8 19:45:52 2000 Brian Gough <bjg@network-theory.co.uk>
* reorganized, made internal functions static
Thu Nov 16 19:45:19 2000 Brian Gough <bjg@network-theory.co.uk>
* qag_impl.c (gsl_integration_qag_impl): replace use of volatile
with the macro GSL_COERCE_DBL
Wed May 31 19:35:57 2000 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): increased tolerances on some results to allow
tests to pass with other compilers
Mon May 15 14:21:00 2000 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): increased one test limit slightly to allow for
rounding errors
Wed Feb 23 14:35:31 2000 Brian Gough <bjg@network-theory.co.uk>
* qpsrt.c (qpsrt): changed ordering of while conditions to avoid
segmentation faults due to accessing values before testing end of
loop condition. Thanks to Brett Viren
<bviren@superk.physics.sunysb.edu> for pointing this out.
* qelg.c (qelg): changed update of nres from the original quadpack
so that uninitialized elements of the res3la array are never
accessed.
* test.c (main): eliminate small memory leak from test
Mon Feb 14 13:45:04 2000 Brian Gough <bjg@network-theory.co.uk>
* qk.c: renamed function qk to gsl_integration_qk since it is
exported
* err.c: made internal function rescale_err static, only used in
qk.c and qng.c
Mon Jul 12 11:37:55 1999 Brian Gough <bjg@network-theory.co.uk>
* qawc_impl.c (gsl_integration_qawc_impl): removed, no longer
necessary since everything goes into qawc.c
Fri Apr 2 20:57:09 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* qelg.c (qelg): removed debugging code
* qpsrt.c (qpsrt): removed debugging code
Thu Mar 11 15:15:46 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* qags_impl.c (gsl_integration_qags_impl): removed dependency in
quadrature function calls by introducing dummy variables resabs1
and resabs2
Wed Mar 10 19:05:41 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* added integrators QAGI, QAGIU, QAGIL for infinite and
semi-infinite ranges
1999-01-01 Mark Galassi <rosalia@cygnus.com>
* integration.c: replaced strings.h with string.h, which is the
ISO library way.
Sat Nov 21 12:43:03 1998 Brian Gough <bjg@vvv.lanl.gov>
* Makefile.am (libgslintegration_a_SOURCES): eliminated local
max.h in favor of global GSL_MAX
* added missing gsl_math.h headers for new GSL_DBL_EPSILON macros
Tue Nov 17 17:16:51 1998 Brian Gough <bjg@vvv.lanl.gov>
* added #include <config.h> to all top-level source files
Fri Jun 12 22:30:21 1998 Brian Gough <bjg@vvv.lanl.gov>
* qage_impl.c: started using volatile (selectively) to enforce
strict IEEE behavior for the branches where it matters. I was
going to use gcc's -ffloat-store option but it didn't work for me.
Using volatile is not really a complete solution but is probably
close enough for all practical purposes (also it doesn't degrade
the performance as much as -ffloat-store would).
Sat May 30 15:40:51 1998 Brian Gough <bjg@vvv.lanl.gov>
* test.c (main): basic tests of qage are now complete
* qage_impl.c (gsl_integration_qage_impl): fixed serious bug for
index i, which was incremented at the end of the do loop and
give an extra undefined entry in the result list!
