Changes for version 2.53_3
- Aug 31 2010
- Added early return to poly_sturm_chain() when it's passed a constant or a linear equation (yeah, I know, but one still has to check).
- A couple more tests each for sturm0.t and sturm1.t.
- Finally use (and then fix) sturm_sign_chain().
- Expose some more internal functions under the :sturm tag, and document them.
Changes for version 2.53_2
- Aug 26 2010
- Added another (cubic) test to cubic.t and poly0.t.
- Aug 25 2010
- CPAN testers found a failing test in sturm0.t for some machines. Altered the test to make use of fltcmp(), which I hope will solve what I suspect is a precision problem.
- Made consistent the book references in the Acknowledgements section.
Changes for version 2.53_1
- Aug 23 2010
- poly_real_roots() becomes poly_real_root_count().
- Added test files sturm0.t and sturm1.t.
- Many documentation additions. Of note: the documentation notes the FUTURE DEPRECATION of set_hessenberg() and get_hessenberg().
- Set $VERSION to reflect beta condition, particularly the (lone) sturm function.
- Aug 14 2010
- Added poly_real_roots().
- Jul 22 2010
- Added the functions to create the sign rows, currently named sturm_sign_minus_infinity(), sturm_sign_plus_infinity(), and sturm_sign_chains().
- Jul 21 2010
- Added function poly_sturm_chain(). Started a test file for it.
- Added a test file for the poly_division() function and of course made the function available under the :utility tag.
- Jun 24 2010
- Stefan Petrea suggested adding Sturm's sequence to the module. After looking it up, it seemed like a good idea, so I began by:
- Added poly_derivative() to the export list and to the :utility tag.
- Added poly_antiderivative() to the export list and to the :utility tag, mostly for completeness's sake, although I may find a legitimate use for it.
- Jun 22 2010
- Added epsilon() to the export list and to the :utility tag. It existed in v2.52, I just forgot to add it, to the export list.
- Formatting changes to the POD with respect to the functions' documentation.
- Math::Polynomial::Solve - Find the roots of polynomial equations.
