Luc Maisonobe created MATH-960:
----------------------------------
Summary: ODE integrator do not handle some additional equations
properly
Key: MATH-960
URL: https://issues.apache.org/jira/browse/MATH-960
Project: Commons Math
Issue Type: Bug
Affects Versions: 3.1.1
Reporter: Luc Maisonobe
Assignee: Luc Maisonobe
Fix For: 3.2
Differential equations may be split as a primary equation and several secondary
equations. In some cases, the secondary equations may have an effect on he
primary derivatives. This can be handled using the method
computeDerivatives(double t, double[] primary, double[] primaryDot, double[]
secondary, double[] secondaryDot) from the SecondaryEquations interface.
However, when the secondary equations updateds the primaryDot array using this
method, the update is ignored.
