2003-01-25 Brian Gough <brian.gough@network-theory.co.uk>
* math.c (gsl_complex_arccsc_real): fixed bug for incorrect sign
of imaginary part when -1<a<0
Wed Dec 11 13:17:21 2002 Brian Gough <brian.gough@network-theory.co.uk>
* math.c (gsl_complex_arg): enforce special case arg(0,0) = 0.0
Mon Sep 10 22:57:27 2001 Brian Gough <bjg@network-theory.co.uk>
* math.c (gsl_complex_div_real gsl_complex_div_real): added
missing functions div_real and div_imag
Mon Aug 27 18:58:41 2001 Brian Gough <bjg@network-theory.co.uk>
* test.el: trim the tests down to a more reasonable size
Thu Aug 9 15:48:48 2001 Brian Gough <bjg@network-theory.co.uk>
* math.c (gsl_complex_tanh): improve accuracy for large R
Fri Jul 27 23:29:10 2001 Brian Gough <bjg@network-theory.co.uk>
* math.c (gsl_complex_cos): avoid returning negative zero for the
imaginary part when the argument is purely real
Wed Mar 21 14:40:34 2001 Brian Gough <bjg@network-theory.co.uk>
* gsl_complex.h (GSL_COMPLEX_P): added macro to point to beginning
of complex array within the struct
Mon Dec 4 12:29:12 2000 Brian Gough <bjg@network-theory.co.uk>
* math.c (gsl_complex_rect): changed the function gsl_complex_xy
to gsl_complex_rect, since this is more meaningful
Sun Oct 22 13:55:09 2000 Brian Gough <bjg@network-theory.co.uk>
* math.c: changed calls to gsl_hypot() to hypot() so that the
system function is used in preference (the configure script will
define hypot to gsl_hypot if hypot is unavailable), similar change
for functions log1p and gsl_log1p also
Wed Mar 15 11:17:21 2000 Brian Gough <bjg@network-theory.co.uk>
* gsl_complex.h: moved into complex/ subdirectory from top-level
