Detailed Description

Base class implementing a numerical integrator.

Class represents an integrator, which calculates the state of the system based on the initial state and a time step. Overloading this class allows implementation of various integrating algorithms.

Constructor & Destructor Documentation

Integrator::Integrator

(

double

stepSize = 0.01

)

Constructor.

Parameters

stepSize

Initial step size

Member Function Documentation

virtual StateVector Integrator::next ( StateVector  state, DiffEq *  equation, double  step = 0.0  )

pure virtual

Function returning the next value of the state.
