Luc Maisonobe commented on MATH-726:
------------------------------------
If we want to implement derivatives, I would rather set up a top level
interface and several implementations, including this one. We could for example
import the definitions from Nabla core package
([http://svn.apache.org/viewvc/commons/sandbox/nabla/trunk/src/main/java/org/apache/commons/nabla/core/])
and the implementations of Nabla numerical package
([http://svn.apache.org/viewvc/commons/sandbox/nabla/trunk/src/main/java/org/apache/commons/nabla/numerical/]).
Of course, once imported these packages would be removed from Nabla itself and
replaced by a dependency to Math.
