| |
| Sun Feb 18 15:35:25 2001 Brian Gough <bjg@network-theory.co.uk> |
| |
| * fdfsolver.c fsolver.c: changed so that the solver _alloc |

| |
| Wed May 17 11:37:15 2000 Brian Gough <bjg@network-theory.co.uk> |
| |
| * test_macros.c (test_macros): use GSL_POSINF and GSL_NAN macros |

| |
| Wed Nov 3 11:59:35 1999 Brian Gough <bjg@network-theory.co.uk> |
| |

| |
| * test.c (main): added a call to gsl_ieee_env_setup for testing |
| |
| * test_roots.c: increased the maximum number of iterations to 150 |
| so that the tests still work on the difficult cases. |
| |
| * steffenson.c (steffenson_iterate): add a check to avoid division |
| by zero |
| |
| Sat Oct 16 19:43:14 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * removed GSL_ROOT_EPSILON_BUFFER, not needed anymore |
| |
| Wed Jul 21 18:47:01 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * gsl_roots.h, convergence.c: changed order of relative and |
| absolute errors to make them the same as quadpack routines |
| (abs,rel) |
| |
| Wed Jul 21 16:30:56 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * brent.c (brent_iterate): fixed bug where bounding interval could |
| be incorrect and not include root. |
| |
| Mon Mar 1 15:38:06 1999 Brian Gough <bjg@netsci.freeserve.co.uk> |
| |
| * moved static class data out of gsl_root_fsolver and |
| gsl_root_fdfsolver and into gsl_root_fsolver_type and |
| gsl_root_fdfsolver_type |
| |
| |
| Mon Mar 1 15:38:06 1999 Brian Gough <bjg@netsci.freeserve.co.uk> |
| |
| * renamed f_solver to fsolver and fdf_solver to fdfsolver, since |
| these look neater |
| |
| Sun Feb 28 21:11:21 1999 Brian Gough <bjg@netsci.freeserve.co.uk> |
| |
| * rewrote the root finding functions in an iterative framework |
| |
| Tue Nov 17 16:47:09 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * secant.c, falsepos.c newton.c: added gsl_math.h to included |
| headers to import GSL_MAX and GSL_MIN |
| |
| Mon Nov 9 21:21:45 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * roots.h: got rid of local MAX(a,b) and MIN(a,b) definitions |
| since they are now in config.h |
| |
| Wed Nov 4 16:08:32 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * test.c (test_brent): allow the brent tests to run for more |
| iterations since they take longer on the pathological cases. |
| |
| * brent.c (gsl_root_brent): on each iteration keep track of |
| current best estimates of the root and the bounds so that they are |
| returned to the user if the function exits prematurely. |
| |
| clean up the brent algorithm based on remarks in the original |
| paper |
| |
| Mon Oct 26 16:31:21 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * in all routines with upper and lower bounds if a root is found |
| exactly then the bracket is collapsed onto the root instead of |
| being untouched. |
| |
| Thu Oct 15 13:59:30 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * bisection.c, falsepos.c, secant.c: reordered the tests so that |
| the minimum number of function evaluations are performed when |
| there is an early exit due to one of the supplied limits lying on |
| a root. |
| |
| Fri Aug 21 14:48:13 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * test.c: clean up of tests to get rid of warnings |
| |
| Thu Aug 20 10:21:15 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * roots.h (_WITHIN_TOL): added extra parens in macro definition, |
| for safety |
| |
| * falsepos.c (gsl_root_falsepos): removed test for absolute |
| equality and replaced by a flag indicating which variables |
| changed. |
| |
| * test.c (main): simplified the tests, removed command line |
| arguments (can use the debugger to select which ones to run) |
| |
| Mon Jun 15 22:22:54 1998 Brian Gough <bjg@vvv.lanl.gov> |
| |
| * started to eliminate void * arguments for function types (they |
| are not a good idea and can easily be specified) |
| |
| 1998-02-09 Mark Galassi <rosalia@cygnus.com> |
| |
| * test.c (main): added an extra argument so that the $(srcdir) can |
| be passed along when "make check" is run in a separate build |
| directory. |
| |
| * test-macros, test-secant, test-bisection, test-newton, |
| test-falsepos: modified these to use build and source directories |
| explicitly. Now "make check" in a separate build directory works. |
| |
| 1998-02-02 Mark Galassi <rosalia@cygnus.com> |
| |
| * Makefile.am (TESTS): added $(srcdir) before these scripts, since |
| the TESTS target picks things from the build directory. |
