Detailed Description

template<int RANK, typename V, bool IS_FAST>
class quantumtrajectory::Master< RANK, V, IS_FAST >

An Adaptive trajectory class representing Master equation evolution from a density-operator initial condition.

Description of the Master-equation evolution.
Note
The ODE driver underlying this class needs to store several (typically 6–7, this depends on the chosen driver) density-operator instants.
Template Parameters
RANKarity of the Hilbert space
Vhas the same function as the template parameter V in display_densityoperator::_, which class is used here for deriving quantum averages to display from the evolved density operator
IS_FASTthe class will use either blitzplusplus::basi::Iterator or blitzplusplus::basi_fast::Iterator to perform the multi-matrix multiplications, depending on this template argument
