Create degradation functions for known analytical solutions

create_deg_func(spec, use_of_ff = c("min", "max"))

Arguments

spec

List of model specifications as contained in mkinmod objects

use_of_ff

Minimum or maximum use of formation fractions

Value

Degradation function to be attached to mkinmod objects

Examples
