Detailed Description

Essentially an aggregate of data fields for logging during a MCWF_Trajectory run.

Different log levels are to be supplied as the first parameter to Logger::Logger, and mean the following:

logLevel	effect
<=1	No log output during the trajectory.
>0	Summary log information at the end of the trajectory display
>1	Reporting jumps on `std::cout` also during trajectory evolution.
>2	Reporting `dpLimit` overshoots and the resulting stepsize decrease also during trajectory evolution.
>3	Reporting number of failed ODE steps in the given step of the trajectory evolution.

Constructor & Destructor Documentation

quantumtrajectory::mcwf::Logger::Logger	(	int	logLevel,
		bool	isHamiltonian,
		size_t	nLindblads
	)

Straightforward constructor.

Parameters

logLevel	governs amount of log output during trajectory display
isHamiltonian	some log information (logFailedSteps & hamiltonianCalled) makes sense only if the simulated system is derived from structure::Hamiltonian
nLindblads	number of Lindblad operators
