CurrentKernel() [1/2]

RealTimeTransport::RenormalizedPT::CurrentKernel::CurrentKernel	(	const std::unique_ptr< Model > &	model,
		int	r,
		Order	order,
		SciCore::Real	tMax,
		SciCore::Real	errorGoal,
		int	block = -1 )

Computes the current kernel for a given model.

Parameters

model	The model for which the current kernel is computed.
r	Index of the reservoir \( r=0,1,\dots \)
order	The order of the renormalized perturbation series.
