Classical Runge-Kutta for system of equations
Description
Classical Runge-Kutta of order 4.
Usage
rk4sys(f, a, b, y0, n, Pars, ...)
Arguments
f |
function in the differential equation |
a |
starting time for the interval to integrate |
b |
ending time for the interval to integrate. |
y0 |
starting values at time |
n |
the number of steps from a to b. |
Pars |
named list of parameters passed to f |
... |
additional inputs to function |
Details
Classical Runge-Kutta of order 4 for (systems of) ordinary differential equations with fixed step size. Copied from pracma under GPL-3, with small modifications to work with RTMB
Value
List with components x for grid points between a and b and y an n-by-m matrix with solutions for variables in columns, i.e. each row contains one time stamp.
