Detailed Description

template<integer dims, typename nelem = number, class NT = NumericTraits<nelem,dims>> class MODEL::Integrator

Integrator: take a step dt from here to the next point

Definition at line 39 of file integrator.h.

Constructor & Destructor Documentation

Integrator ( vf & d, vf & s ) [inline]

Set the integrator and tell it what to do. At the moment any special cases with for example correlated noise should be taken care of when we derive. I agree that storing a pointer to the function objects inside the base class might not be very kosher, but that's the way it is for now. Cleanup is NOT a priority. Parameters: d   is the deterministic vectorfunction. s   is the multiplicative stochastic vectorfunction. Definition at line 58 of file integrator.h.

Member Function Documentation

vect & currentpoint ( void ) [inline]

Return current point Definition at line 73 of file integrator.h.

vf * get_deterministic ( void ) [inline, private]

Get functions - not clean, but necessary Definition at line 77 of file integrator.h.

vect & step ( vect & current, time & dt ) [pure virtual]

Implement this one to take a step. takes the current point and modifies it. Returns a ref to the modified point Parameters: dt   is the step to take. This makes it possible to generate a adaptive stepsize if needed. I wonder if the fact that an Integrator has a dt makes it a candidate for TickTock status? Reimplemented in MODEL::IEuler, MODEL::IRungeKutta, MODEL::IMilshtein, and MODEL::IHeunSimpleCorr.
