class
DCProgs::ApproxSurvivor¶ Implementation of asymptotic missed events.
This object merely puts together two Asymptotes objects.
Subclassed by DCProgs::MissedEventsG
Public Types
-
typedef
std::function<std::vector<Root>DeterminantEq const &)> DCProgs::ApproxSurvivor::t_RootFinder Type of the function used to minimize roots.
Public Functions
-
ApproxSurvivor(DeterminantEq const &_af, std::vector<Root> const &_roots_af, DeterminantEq const &_fa, std::vector<Root> const &_roots_fa)¶ Initializes approximate survivor functor.
- Parameters
_af-Determinant equation for open->shut transitions
_roots_af-Roots of _af equation
_fa-Determinant equation for shut->open transitions
_roots_fa-Roots of _fa equation
-
ApproxSurvivor(QMatrix const &_matrix, t_real _tau, t_RootFinder const &_findroots)¶ Initializes approx survivor functor.
- Parameters
_matrix-Transition matrix
_tau-resolution/max length missed events
_findroots-A functor with which to find all roots. This function should take a DeterminantEq as its sole argument and return a std::vector<DCProgs::RootInterval>
-
ApproxSurvivor(ApproxSurvivor &&_c)¶ Move constructor.
-
ApproxSurvivor(QMatrix const &_qmatrix, t_real _tau, t_real _xtol = 1e-12, t_real _rtol = 1e-12, t_uint _itermax = 100, t_real _lowerbound = quiet_nan, t_real _upperbound = quiet_nan)¶ Initializes missed-events functor.
- Parameters
_qmatrix-Transition matrix
_tau-resolution/max length missed events
_xtol-Tolerance for interval size
_rtol-Tolerance for interval size. The convergence criteria is an affine function of the root: \(x_{\mathrm{tol}} + r_{\mathrm{tol}} x_{\mathrm{current}} = \frac{1}{2}|x_a - x_b|\).
_itermax-maximum number of iterations for any of the three steps.
_lowerbound-Lower bound of the interval bracketing all roots. If None, the lower bound is obtained from find_lower_bound_for_roots().
_upperbound-Upper bound of the interval bracketing all roots. If None, the upper bound is obtained from find_upper_bound_for_roots().
-
t_stack_rmatrix
af(t_real _t) const¶ Open to close transitions.
-
t_stack_rmatrix
fa(t_real _t) const¶ Close to open transitions.
