ode.RK4: Solve arbitrary first order ODE systems via fourth-order...

In shill1729/odeSolveR: Implementation of simple Euler schemes and fourth-order Runge-Kutta methods for arbitrary first-order ODE systems

Description

An implementation of the fourth-order Runge-Kutta scheme for arbitrary first-order ODE systems of finite dimension.

Usage

ode.RK4(dynamics, IC, t0 = 0, tn = 1, n = 1000)

Arguments

dynamics	a list of functions defining the dynamics of the system, with as many variables as IC, and in the same order with the names
IC	a list of variables with the same names as the non-time input as f, in the same order with initial values
t0	initial time
tn	ending time
n	number of sub-intervals in time-grid

Details

The list of functions, each of which must have arguments (t,x,y,z) for each element matching the elements of IC as list(x = y0, y = y0, z = z0) for example.

Value

data.frame
