Luc Maisonobe created MATH-1275:
-----------------------------------
Summary: EventHandler and StepHandler interfaces do not provide
derivatives
Key: MATH-1275
URL: https://issues.apache.org/jira/browse/MATH-1275
Project: Commons Math
Issue Type: Bug
Affects Versions: 3.5
Reporter: Luc Maisonobe
Fix For: 4.0
The EventHandler and StepHandler interfaces allow passing the current state
vector to user code, but not its derivatives. This is a pity because the
integrator does know these derivatives as they are the basis from which
everything else is computed. The data is lying around, just not passed to user.
This is a design issue and as it affects user interfaces, it cannot be fixed
before 4.0.
