rkintegrate: A simple Runge-Kutte integrator
Description
Integrates ordinary differential equations using a Runge-Kutta method
Usage
rkintegrate(fun, x0, tstart = 0, tend = 1, dt = NULL)
Arguments
fun
the dynamical function with arguments
state
(a vector) and
t
.
x0
the initial condition, a vector with one element for each state variable
tstart
starting time
tend
ending time for integration
dt
step size for integration
Value
a list containing
x
, a matrix of the state with one row for each time step and a vector
t
containing the times of those steps.
