calculateTransportEquation()

std::vector< double > BSMPT::Baryo::calculateTransportEquation	(	const double &	z,
		const std::vector< double > &	parStart,
		const struct GSL_integration_mubl &	params
	)

Solve the Transport equations using the transport_equations class.

Parameters

z	Distance from the wall (z=0) at which the equations should be solved. The symmetric phase is at z=infinity.
parStart	The boundary conditions in the symmetric phase for the chemical potentials
params	The GSL_integration_mubl struct which contains all necessary informations of the model.

Returns

The values of the chemical potentials at distance z will be stored

eta_integrand_func()

double BSMPT::Baryo::eta_integrand_func	(	double	z,
