boost::numeric::odeint::integrate — Integrates the ODE without observer calls.
// In header: <boost/numeric/odeint/integrate/integrate.hpp> template<typename System, typename State, typename Time> size_t integrate(System system, State & start_state, Time start_time, Time end_time, Time dt);
Integrates the ODE given by system from start_time to end_time starting with start_state as initial condition and dt as initial time step. This function uses a dense output dopri5 stepper and performs an adaptive integration with step size control, thus dt changes during the integration. This method uses standard error bounds of 1E6. No observer is called.
Note  

A second version of this function template exists which explicitly expects the value type as template parameter, i.e. integrate< double >( sys , x , t0 , t1 , dt ); 
Parameters: 


Returns: 
The number of steps performed.
