systemAge

Computes the density distribution and mean for the system and pool ages of a
constant compartmental model in matrix representation

Functions for modeling Soil Organic Matter decomposition
in terrestrial ecosystems with linear and nonlinear systems of differential equations.
The package implements
models according to the compartmental system representation described in
Sierra and others (2012) <doi:10.5194/gmd-5-1045-2012> and Sierra and others (2014)
<doi:10.5194/gmd-7-1919-2014>.
