Julien Anxionnat created MATH-863:
-------------------------------------
Summary: new Quaternion class added in complex package
Key: MATH-863
URL: https://issues.apache.org/jira/browse/MATH-863
Project: Commons Math
Issue Type: New Feature
Affects Versions: 3.1
Reporter: Julien Anxionnat
This patch provides a new class for the mathematical object "Quaternion" in the
complex package.
This quaternion is considered as a mathematical object (the Hamilton's
hypercomplex number).
Note that it's not a rotation quaternion which has to be a quaternion of norm
one. Although this feature could be used for a getter in the Rotation class.
This patch provides also some improvements in Precision class : a "double
comparison epsilon" and a method to compute relative comparison.
(Please, note that's it's my first contribution, and I apologize in advance for
my mistakes…)
