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.
