| |
| * test.c (main): added tests for linear case |
| |
| * zsolve_quadratic.c (gsl_poly_complex_solve_quadratic): handle |
| the linear case |
| |
| * solve_quadratic.c (gsl_poly_solve_quadratic): handle the linear |
| case |
| |
| 2005-05-19 Brian Gough <bjg@network-theory.co.uk> |
| |
| * Makefile.am (noinst_HEADERS): removed norm.c (unused) |
| |
| Sun Dec 2 22:02:31 2001 Brian Gough <bjg@network-theory.co.uk> |
| |
| * dd.c: added divided differences code from Dan, Ho-Jin |
| |
| Wed Oct 31 18:42:10 2001 Brian Gough <bjg@network-theory.co.uk> |
| |
| * qr.c (qr_companion): increased maximum number of iterations from |
| 30 to 60 |
| |
| Thu Jun 28 11:24:51 2001 Brian Gough <bjg@network-theory.co.uk> |
| |
| * test.c (main): fixed a subtle bug in the test where the array |
| for the complex results was too small by a factor of two |
| |
| Mon Apr 30 12:36:08 2001 Brian Gough <bjg@network-theory.co.uk> |
| |
| * eval.c (gsl_poly_eval): added eval function from specfunc |
| |
| Tue Aug 24 12:02:47 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * zsolve.c: added general solver using QR method |
| |
| 1999-08-22 Mark Galassi <rosalia@lanl.gov> |
| |
| * Makefile.am (libgslpoly_a_SOURCES): for now commented out |
| zsolve.c, since it has some strange errors that make it look like |
| it was not committed. |
| |
| Tue Aug 17 14:23:47 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * zsolve_cubic.c (gsl_poly_complex_solve_cubic): compute the |
| discriminant without division so that it is exact for exact inputs |
| |
| * solve_cubic.c (gsl_poly_solve_cubic): compute the discriminant |
| without division so that it is exact for exact inputs |
| |
| * changed the way roots are counted to make all the routines |
| consistent. Conincident roots are no longer a special case, now |
| they are made up of separate roots which happen to have the same |
| values. |
| |
| * zsolve_quadratic.c (gsl_poly_complex_solve_quadratic): in the |
| case of a multiple root set all the returned values r0 = r1 = |
| root, rather than just setting one and leaving the others |
| potentially unset. |
| |
| * solve_quadratic.c (gsl_poly_solve_quadratic): ditto |
| |
| Tue Aug 3 19:36:26 1999 Brian Gough <bjg@network-theory.co.uk> |
| |
| * gsl_poly.h: changed all functions to take separate variables for |
| roots (z0, z1, z2) of variable-length arrays |
| |
| Sat Feb 20 12:13:46 1999 Brian Gough <bjg@netsci.freeserve.co.uk> |
| |
| * split out polynomial root finding algorithms into a new poly/ |
| directory |
