Package org.hipparchus.migration.ode
Interface SecondaryEquations
- All Superinterfaces:
SecondaryODE
Deprecated.
This interface allows users to add secondary differential equations to a primary
set of differential equations.
In some cases users may need to integrate some problem-specific equations along with a primary set of differential equations. One example is optimal control where adjoined parameters linked to the minimized hamiltonian must be integrated.
This interface allows users to add such equations to a primary set of first order differential equations
thanks to the ExpandableODE.addSecondaryEquations(SecondaryODE)
method.
