## 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,
                       double[] yDot)
                         throws MathIllegalStateException,
                                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)
