Interface SecondOrderIntegrator

All Superinterfaces:
ODEIntegrator

public interface SecondOrderIntegrator
extends ODEIntegrator

This interface represents a second order integrator for differential equations.

The classes which are devoted to solve second order differential equations should implement this interface. The problems which can be handled should implement the SecondOrderDifferentialEquations interface.

void integrate(SecondOrderDifferentialEquations equations,
               double t0,
               double[] y0,
               double[] yDot0,
               double t,
               double[] y,

                      MathIllegalArgumentException
Integrate the differential equations up to the given time

Parameters:
equations - differential equations to integrate
t0 - initial time
y0 - initial value of the state vector at t0
yDot0 - initial value of the first derivative of the state vector at t0
t - target time for the integration (can be set to a value smaller thant t0 for backward integration)
y - placeholder where to put the state vector at each successful step (and hence at the end of integration), can be the same object as y0
yDot - placeholder where to put the first derivative of the state vector at time t, can be the same object as yDot0
Throws:
MathIllegalStateException - if the integrator cannot perform integration
MathIllegalArgumentException - if integration parameters are wrong (typically too small integration span)
