AbstractODESolver class

Defines the basic methods for all the ODE solvers.

AbstractODESolver generic

AbstractODESolver constructor missing

AbstractODESolver constructor ODE. Uses this constructor when ODE object is passed

AbstractODESolver(ode, ...)

# S4 method for AbstractODESolver
step(object, ...)

# S4 method for AbstractODESolver
getODE(object, ...)

# S4 method for AbstractODESolver
setStepSize(object, stepSize, ...)

# S4 method for AbstractODESolver
init(object, stepSize, ...)

# S4 method for AbstractODESolver
init(object, ...) <- value

# S4 method for AbstractODESolver
getStepSize(object, ...)

# S4 method for missing
AbstractODESolver(ode, ...)

# S4 method for ODE
AbstractODESolver(ode, ...)

Arguments

ode	an ODE object
...	additional parameters
object	a class object
stepSize	the size of the step
value	the step size value

Inherits from: ODESolver class

Examples

# This is how we start defining a new ODE solver: Euler
.Euler <- setClass("Euler",              # Euler solver very simple; no slots
     contains = c("AbstractODESolver"))



# Here we define the ODE solver Verlet
.Verlet <- setClass("Verlet", slots = c(
    rate1 = "numeric",                          # Verlet calculates two rates
    rate2 = "numeric",
    rateCounter = "numeric"),
contains = c("AbstractODESolver"))



# This is the definition of the ODE solver Runge-Kutta 4
.RK4 <- setClass("RK4", slots = c(       # On the other hand RK4 uses 4 rates
   rate1 = "numeric",
   rate2 = "numeric",
   rate3 = "numeric",
   rate4 = "numeric",
   estimated_state = "numeric"),         # and estimates another state
contains = c("AbstractODESolver"))
