Changes for version 2.62_2
- Jan 2 2012
- And more tests added to derivaluate.t. Up to CPAN we go.
- Dec 23 2011
- Bug in poly_derivaluat(). For polynomials degree 5 or higher, was returning the wrong second derivative value. Unfortunately, the testing of the function was only done indirectly in laguerre.t, and it, only had third degree polynomials. Extended laguerre.t, and added derivaluate.t to test files.
- Nov 17 2011
- Perl version requirement changed to 5.8.3 (from 5.6.0). Support for 5.6.0 in various perl development tools is being dropped, and 5.8.3 seems to be a safe minimum, at least for the next year or so. Change made in Build.PL and Solve.pm.
- Changed "repository" key in Build.PL from a hash to a string, as seems to be currently required under the version of Module::Build that I'm developing with (the hash form looks to be for a later version that I cannot install yet).
Changes for version 2.61_1
- Oct 30 2011
- A couple more changes to Build.PL (dist_author and resources). Time to push this up to git and add it to CPAN.
- Sep 20 2011
- CPAN::Meta::Spec had a lot to say about the changes to Build.PL scripts. Made those changes.
- Sep 19 2011
- The pre-September items for this version were done separate from the git and github installation. Merged it all in.
- Sep 9 2011
- Added carp messages to get_hessenberg() and set_hessenberg(). Now anyone still using these functions gets nagged about it.
- July 20 2011
- Emphasize in the documentation the fact that roots are mixed real and Math::Complex - there was some confusion.
- Mar 24 2011
- Gah. EXPORT list didn't have poly_tolerance!
- Put in a check for accidental refs in poly_derivaluate().
- Mar 23 2011
- Test file nr.t created, and added to MANIFEST.
- A couple more keywords added to Build.PL.
- Mar 12 2011
- Added Newton-Raphson function newtonraphson() to the module, just to provide a comparison with laguerre().
- Added Newton-Raphson to the keyword list.
- Mar 9 2011
- New function poly_derivaluate(), to be used internally by laguerre(). Added it to the :utility EXPORT list.
- laguerre() now uses poly_derivaluate().
- Documented poly_derivaluate().
- Fixed an L<> typo.
- Improved the Sturm function documentation.
- Mar 2 2011
- Three more tests to cubic.t (polynomial representations of trisecting a 60 deg. angle; duplicating the cube; and construction a septagon; all with straightedge and compass).
- Instead of a copy of the @cases in cubic.t with negative coefficients, just use poly_constmult() in the loop.
- Did the same to quartic.t.
- And quadratic.t.
