3 * eval.c: added functions for complex polynomials
5 2005-07-03 Brian Gough <bjg@network-theory.co.uk>
7 * test.c (main): added tests for linear case
9 * zsolve_quadratic.c (gsl_poly_complex_solve_quadratic): handle
12 * solve_quadratic.c (gsl_poly_solve_quadratic): handle the linear
15 2005-05-19 Brian Gough <bjg@network-theory.co.uk>
17 * Makefile.am (noinst_HEADERS): removed norm.c (unused)
19 Sun Dec 2 22:02:31 2001 Brian Gough <bjg@network-theory.co.uk>
21 * dd.c: added divided differences code from Dan, Ho-Jin
23 Wed Oct 31 18:42:10 2001 Brian Gough <bjg@network-theory.co.uk>
25 * qr.c (qr_companion): increased maximum number of iterations from
28 Thu Jun 28 11:24:51 2001 Brian Gough <bjg@network-theory.co.uk>
30 * test.c (main): fixed a subtle bug in the test where the array
31 for the complex results was too small by a factor of two
33 Mon Apr 30 12:36:08 2001 Brian Gough <bjg@network-theory.co.uk>
35 * eval.c (gsl_poly_eval): added eval function from specfunc
37 Tue Aug 24 12:02:47 1999 Brian Gough <bjg@network-theory.co.uk>
39 * zsolve.c: added general solver using QR method
41 1999-08-22 Mark Galassi <rosalia@lanl.gov>
43 * Makefile.am (libgslpoly_a_SOURCES): for now commented out
44 zsolve.c, since it has some strange errors that make it look like
47 Tue Aug 17 14:23:47 1999 Brian Gough <bjg@network-theory.co.uk>
49 * zsolve_cubic.c (gsl_poly_complex_solve_cubic): compute the
50 discriminant without division so that it is exact for exact inputs
52 * solve_cubic.c (gsl_poly_solve_cubic): compute the discriminant
53 without division so that it is exact for exact inputs
55 * changed the way roots are counted to make all the routines
56 consistent. Conincident roots are no longer a special case, now
57 they are made up of separate roots which happen to have the same
60 * zsolve_quadratic.c (gsl_poly_complex_solve_quadratic): in the
61 case of a multiple root set all the returned values r0 = r1 =
62 root, rather than just setting one and leaving the others
65 * solve_quadratic.c (gsl_poly_solve_quadratic): ditto
67 Tue Aug 3 19:36:26 1999 Brian Gough <bjg@network-theory.co.uk>
69 * gsl_poly.h: changed all functions to take separate variables for
70 roots (z0, z1, z2) of variable-length arrays
72 Sat Feb 20 12:13:46 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
74 * split out polynomial root finding algorithms into a new poly/
