-XA -n Math::Yapp
This is the first release. No changes to report.
1.02 Sun Oct 06 23:33:28 2013
Successfully released to CPAN a couple of days ago and finally
managed to see what the POD looks like. YIKES! This inspired
two modifications:
- Immediately set to correcting typos and unclear remarks in the POD.
(I doubt it's perfect now.)
- Added method Yapp_negate_roots(), which produces a polynomial whose
roots are the negatives of the given polynomial. (I hadn't realized
that omission until I read the POD.)
1.03 Mon Oct 14 11:20:12 2013
- Commented out [use Math::BigFLoat;] and the call to
Math::BigFLoat->accuracy() in the BEGIN block. This because the
BUGS section of Math::Complex warns me not attempt to use BigFloat.
I left these stantements in there as comments as a reminder that I
need to do something about the accuracy; 64 (or 80?)-bit floats
don't quite cut it for polynomials above degree 8.
Yes, this leaves a no-op BEGIN block. But who knows what I'll come
up with in a future release?

- Fixed minor error in Interpolation testing module that raise
compiler warnings.
- Added code for Hermite interpolation test to use 6-points,
instead of only 4 points, when running in a 64-bit environment.
Note that at 7 points the rounding errors become too gross to
pass muster.
- Added method "YinnerProd", an innner product function,
overloaded by the . operator.
1.06 Fri, May 15, 2015 11:36:55 AM
- Completed more on innr-product space issues
- Added complete documentation on inner-product space functionality,
including a mea-culpa on what I have ot yet done
