In ecostate: State-Space Mass-Balance Model for Marine Ecosystems

Adams-Bashford-Moulton for system of equations

Description

Third-order Adams-Bashford-Moulton predictor-corrector method.

Usage

abm3pc_sys(f, a, b, y0, n, Pars, ...)

Arguments

f	function in the differential equation y' = f(x, y); defined as a function R \times R^m \rightarrow R^m, where m is the number of equations.
a	starting time for the interval to integrate
b	ending time for the interval to integrate.
y0	starting values at time a
n	number of steps
Pars	named list of parameters passed to f
...	additional inputs to function f

Details

Combined Adams-Bashford and Adams-Moulton (or: multi-step) method of third order with corrections according to the predictor-corrector approach. 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.
