Member Function Documentation

int RGE::callRK	(	double	x1,
		double	x2,
		DoubleVector &	v,
		DoubleVector(*)(double, const DoubleVector &)	derivs,
		double	eps = -1.0
	)

Does the actual calling of Runge Kutta: default precision is TOLERANCE. Returns >0 if there's a problem with the running. IO parameters: x1=start renormalisation scale, x2=end renormalisation scale, v=boundary condition on parameters to be run on input, but gets changed to calculated final values on output, function to calculate derivatives are encoded in *derivs, eps is the numerical accuracy

virtual const DoubleVector RGE::display

(

)

const [pure virtual]

Displays all RGE parameters in a double vector. Obligatory function for derived classes.

Implemented in MssmSusy, QedQcd, SoftParsMssm, and RpvSoftsusy.

virtual void RGE::set

(

const DoubleVector &

s

)

[pure virtual]

Sets all parameters in an RGE object to the contents of s. It's an obligatory function for a derived class.

Implemented in SoftParsMssm, MssmSusy, QedQcd, and RpvSoftsusy.

virtual void RGE::setmu

(

double

f

)

[inline, virtual]

Default is to just set mu, but if you've got a derived class, you may like to call several setMu's.

void RGE::setThresholds

(

int

t

)

[inline]

Set level of threshold approximation used. It's typically used in the beta functions or boundary conditions.
