Detailed Description

Class for integrating ODEs using a Runge-Kutta-Fehlberg method.

This class makes use of the 8th order Runge-Kutta-Fehlberg algorithm provided by the odeint library in Boost.

Member Function Documentation

operator()()

void flexiblesusy::runge_kutta::RKF_integrator::operator()	(	double	start,
		double	end,
		Eigen::ArrayXd &	pars,
		const Derivs &	derivs,
		double	tol
	)		const

Integrates the system over an interval.

The vector of the initial values of the parameters is updated so that after calling this function, this vector contains the updated values of the parameters at the end-point of the integration.

Parameters

[in]	start	initial value of the independent variable
[in]	end	final value of the independent variable
[in,out]	pars	initial values of the parameters
[in]	derivs	function calculating the derivatives
[in]	tol	desired accuracy to use in integration step
